Extend and retract the new latch or deadbolt by hand. If it binds with the door open, correct the lock or latch installation before touching the strike plate. If it works smoothly open but binds only when the door is closed, the problem is usually alignment, strike clearance, door fit, or pressure from weatherstripping.
The safest repair is to identify exactly where the bolt rubs, then make the smallest correction needed. A strike adjustment may solve an edge contact; a carefully enlarged pocket may be needed when wood blocks bolt travel. Do not chisel or widen the frame until you have marked the contact point and checked the lock’s installation instructions.

Use the open-versus-closed test first
This test separates a lock-installation problem from a door-and-frame problem. Keep the door open so the bolt cannot contact the strike, and operate the lock manually. It should extend and retract smoothly without unusual force.

| What you observe | Most likely area | Next move |
|---|---|---|
| The latch or deadbolt binds with the door open | Latch selection, orientation, door handing, mounting tension, or another installation detail | Recheck the lock’s model-specific installation instructions and latch installation |
| The lock works open but binds when the door is closed | Strike alignment, pocket depth, door fit, hinges, or weatherstripping | Mark the contact point and inspect the strike and frame |
| The door will not close flush without pushing or pulling | Door fit, weatherstripping, hinge sag, or frame movement | Correct the closing pressure or door position before adjusting the strike |
| The bolt enters the opening but stops against its back or side | A shallow or obstructed strike pocket | Measure the pocket and remove only the material confirmed to obstruct travel |
Schlage’s installation guidance uses the same basic sequence: test the deadbolt with the door open, then test it closed. Kwikset likewise advises closing the door and operating a smart lock manually without pushing or pulling it. Resistance that appears only after closing points toward alignment between the bolt and strike opening.

Gather the right tools and protect the lock
Most adjustments require only a screwdriver and a way to mark the bolt. A #2 Phillips screwdriver is suitable for the installation screws specified in Schlage’s instructions. Avoid using an electric drill on lock screws; excessive torque can strip the screws or damage the lock.
- A #2 Phillips screwdriver
- Chalk or lipstick for transferring the contact mark
- A flashlight for viewing the strike pocket
- A sharp wood chisel, used only when the marked obstruction is in a wood frame
- The installation guide for the exact lock model
Keep the door supported while working. Do not leave a partially secured exterior door unattended, and do not remove all hinge or strike screws at once.
Step 1: Test the latch or deadbolt with the door open
- Open the door fully and keep it clear of the frame.
- Turn the thumb turn, key, or interior lever through its complete travel.
- Watch the latch or deadbolt extend and retract. It should move straight and smoothly.
- Repeat the movement several times. Do not force a mechanism that stops or grinds.
If the bolt binds in this position, the strike is not causing the immediate problem. Check that the latch is the part specified for the lock, that its tapered face points toward the strike as required, and that it is not installed upside down. Confirm that the lock’s mounting plate and through-bolts are seated correctly rather than pulling the mechanism out of alignment.

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsSome electronic locks require a door-handing or handing procedure so the motor knows which way the door opens. Kwikset identifies a missed handing procedure, an old non-tapered latch, an upside-down latch, and excessive mounting-plate tension as possible causes on SmartCode 909 and 910 models. Those checks are specific to those model families; use your own lock’s manual for the correct sequence rather than applying a different model’s procedure.

- One-Handed Loading - Keep one hand free with a 1/4 in. hex chuck that accepts 1 in. bit tips
Step 2: Test with the door closed, without force
- Close the door normally, without lifting, pulling, or pushing it.
- Operate the latch or deadbolt by hand, not with the motor, if the lock design allows it.
- Notice whether the bolt meets an edge, rubs along a face, or stops before reaching the full depth.
- Open the door and compare the bolt position with the strike opening.
If the mechanism is smooth open and difficult only when closed, concentrate on the door-to-strike relationship. A new lock can expose an existing alignment problem because its bolt may sit at a different height, depth, or side-to-side position than the previous hardware.
Step 3: Mark the exact contact point
Do not start filing or chiseling based on a visual guess. Schlage recommends marking the bolt with chalk or lipstick, then operating it slowly so the mark transfers to the strike or frame.
- Coat the end and sides of the latch or deadbolt lightly with chalk or lipstick.
- Close the door gently until the bolt meets resistance.
- Turn the lock only as far as it will move without force.
- Open the door and inspect the transferred smear on the strike plate or pocket.
- Repeat once if the mark is unclear.
The mark tells you whether the bolt is hitting the upper edge, lower edge, side edge, face of the strike, or the wood behind the opening. That information determines whether to shift the strike, clear the pocket, or correct the door position.
Step 4: Inspect strike alignment and pocket depth
Check the strike opening
With the door open, compare the bolt’s centerline with the strike opening. Look for a strike that is visibly too high, too low, too far toward the hinge side, or too far toward the latch side. Also check whether the strike is tilted or sitting proud of the jamb.

Check behind the strike
The bolt needs an unobstructed recess behind the metal plate. A pocket can be too shallow, packed with paint, filled with debris, or blocked by a previous installation. A bolt that reaches the opening but stops against the wood behind it has a clearance problem, not merely an edge-alignment problem.
Understand the 1-inch guidance
Schlage’s troubleshooting information describes a deadbolt pocket 1 inch deep for the covered installation context. Kwikset’s SmartCode 909/910 instructions likewise call for a frame hole at least 1 inch (25 mm) deep. These are manufacturer instructions for those lock contexts, not a universal dimension for every lock, door, or frame. Check the exact manual for your model before cutting the jamb.
Step 5: Adjust the strike when the bolt hits an edge
If the chalk mark shows contact on the edge of the strike opening, loosen the strike screws and see whether the plate has enough play to move into alignment.
- Back out the strike screws while leaving them engaged in the jamb.
- Move the plate a small amount toward the marked contact area’s opposite side.
- Tighten the screws firmly but do not strip them or pull the plate out of square.
- Close the door and repeat the no-force test.
Use the smallest movement that centers the bolt. If the existing plate cannot provide the necessary clearance, a strike supplied or specified for the installed lock may be appropriate. Match the replacement to the lock and jamb dimensions; do not assume that any plate with a similar opening is compatible.

Step 6: Enlarge a shallow or obstructed pocket carefully
Use a wood chisel only when the transferred mark and depth inspection show that wood is blocking the bolt. Remove material gradually from the marked area, keeping the recess square and deep enough for the bolt to extend without dragging.
- Remove or loosen the strike so you can see the full pocket.
- Mark the exact area requiring clearance.
- Score the edges of the intended recess to reduce splintering.
- Use a sharp chisel with controlled, shallow cuts following the grain.
- Clear dust and chips, reinstall the strike, and test the lock.
- Stop as soon as the bolt travels freely; do not enlarge the entire pocket unnecessarily.
Schlage specifically suggests trying the supplied deadbolt strike if an existing plate limits pocket depth. That can be preferable to cutting a larger recess. Never chisel blindly: removing too much wood can weaken the jamb, expose a gap, or leave the strike unsupported.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Step 7: Check whether the door is closing in the wrong position
Weatherstripping pressure
New or compressed weatherstripping can hold the door slightly away from the jamb. If the latch works when you press the door toward the frame but not when you release it, inspect whether the seal is too thick, folded, or incorrectly positioned. Adjust or replace the weatherstripping so the door closes flush without a hand applying pressure.
Seasonal movement
Wood can swell or move with changes in moisture and temperature. A door that previously latched may shift enough for the new bolt to contact the strike. Look for fresh rubbing along the door edge or jamb and correct the fit before making a large permanent change to the strike.

Hinge sag or loose screws
Loose, worn, or sagging hinges can lower the latch side of the door. Check hinge screws and the gap around the door. If the door lifts when you raise the handle, hinge movement may be the underlying cause. Secure or repair the hinges before relocating the strike; otherwise the alignment may change again.
Step 8: Recheck lock-specific installation details
When the bolt binds even with the door open, or when alignment corrections do not help, return to the lock’s installation guide. Confirm each of the following:
- The latch is the correct part for the lock and door preparation.
- The latch face is oriented correctly, including the tapered side where the instructions require it.
- The latch has not been installed upside down.
- Any required door-handing or calibration procedure has been completed.
- The mounting plate is seated flat and its screws are tight without excessive tension.
- The door thickness is within the lock’s supported range.
- The through-bolts are not overtightened and squeezing the lock body against the door.
For specified Kwikset smart-lock families, support guidance calls out door thickness, through-bolt tension, latch orientation, and handing as installation checks. Do not borrow a setting or procedure from another model simply because the hardware looks similar.
Recommended Free Tools
Choose the correction based on the symptom
| Confirmed symptom | Appropriate correction | What to avoid |
|---|---|---|
| Bolt strikes the upper, lower, or side edge of the strike | Shift the strike slightly and retest | Chiseling the entire opening before trying a small adjustment |
| Bolt reaches the opening but hits wood behind it | Clear the marked pocket area or use the lock-compatible supplied strike | Removing unmarked wood or making the pocket much larger than required |
| Door closes only when pushed or pulled | Correct weatherstripping, hinge movement, or door fit | Forcing the bolt with the door under pressure |
| Lock binds while the door is open | Correct latch selection, orientation, handing, or mounting tension | Moving the strike as a first response |
| Alignment changes after hinge movement or seasonal swelling | Repair the door fit, then realign the strike if needed | Making a permanent large cut for a temporary shift |
Confirm the repair under normal conditions
- With the door open, extend and retract the latch or deadbolt several times.
- Close the door without pushing, pulling, or lifting it.
- Operate the lock by hand and confirm smooth entry and retraction.
- Test the key, thumb turn, lever, or electronic control used for normal operation.
- Check that the door remains latched when you release it and that the bolt is fully extended when locked.
- Open the door and repeat the cycle several times to ensure the result is consistent.
A properly corrected lock should not require you to lean on the door, lift the handle, or pull the door toward you while turning the lock. If it still binds, stop applying force. Reinspect the mark, verify the pocket, and review the model-specific installation steps.
When to replace a part or call for help
Replace the strike only when the existing plate cannot provide the clearance or geometry required by the installed lock, and choose a lock-compatible part. A new strike will not solve a sagging door, an incorrectly installed latch, or a pocket that is blocked behind the plate.
Contact the lock manufacturer or a qualified locksmith when the mechanism binds with the door open after the installation has been checked, when an electronic lock repeatedly fails its handing or calibration procedure, when the door or jamb is damaged, or when correcting the opening would remove substantial structural material. Have the lock model, door thickness, latch type, and a description of whether the problem occurs open, closed, or both ready for support.
Quick Recap
Prevent the problem on the next lock installation
- Read the exact installation guide before removing the old hardware.
- Test the new latch with the door open before tightening every mounting screw fully.
- Keep the original strike until the new lock has passed the closed-door test.
- Mark contact before cutting or filing the jamb.
- Use a hand screwdriver for final tightening so the screws and lock body are not damaged.
- Recheck operation after the door has been closed and opened repeatedly.
