Deadbolt striker is a little too long. Can it be adjusted?

The striker probably needs adjusting - if it is a double sneck latch move the striker out a little and if it is just a single sneck latch it will need moving in.

A tailgate or rear hatch usually closes on to adjustable rubber buffers that often lose adjustment due to them "walking" over time. The aim is to strike a balance between the correct latching of the tailgate and pressure on the rubber buffers so the tailgate doesn't rattle and the finished position is where the gap between the tailgate and body is equal all the way around.

You need to bend the arm on the one hammer back that is making the clunk sound. You will have to experiment a little until you get the sound you are happy with.

You likely have the lever that goes from the outside portion of the lock through the striker/bolt assembly into the inside portion rotated into an incorrect position when you insert it into the striker/bolt assembly.

If after every re-adjustment the trunk close only to refuse to close after sometime, it is posible that striker is not tight enough and probably shifting after some uses. It is likely also that the threads on the bolts or screws are worn lightly. If posible try using a spring washer or some threadlocker medium strenght.

Hi!!
The doors Hinges or Striker need to be adjusted to make up for the weatherstrip thickness. To do this, loosen the hinge-to-door bolts for lateral adjustment only. Loosen the hinge-to-body bolts for both lateral and vertical adjustment.
FRONT DOORS
REAR DOORS

BEFORE YOU START:

• Determine which hinge bolts are to be loosened and back them out just enough to allow movement.
• To move the door safely, use a padded pry bar. When the door is in the proper position, tighten the bolts to 19-25 ft. lbs. (26-35 Nm) and check the door operation. There should be no binding or interference when the door is closed and opened.
• Door closing adjustment can also be affected by the position of the lock striker plate. Loosen the striker plate bolts and move the striker plate just enough to permit proper closing and locking of the door.

HORIZONTAL AND VERTICAL ADJUSTMENT

• Loosen the front door hinge to front door bolts.
• Adjust the front door alignment.
• Tighten the front door hinge to front door bolts to 19-25 ft. lbs. (26-35 Nm).

Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Sounds like a faulty door switch check the door switch and also the door striker adjustment,Is the door sticking out a little? if so just loosen the screws and adjust the striker inwards.

open the door loosen the striker on the door jam and adjust it by slidding it back and forth, also if the door has drooped a little loosen the lower hinge and put a 3/8 shim between the hinge and door!!!

Sounds like the tumbling mechanism for the handle may be off......check to make sure that the screws are tight that lock the front and back of the deadbolt together. Make sure that the door is fully closed and check to see where the deadbolt is hitting the striker. It mat be as simple as the door and frame have expanded a bit and the door is not fully seated when you close the door from the inside. See if these help if not please contact me as I wish to find a solution to your problem.

i'm guessing you have a problem with the release cable?try slipping your credit card in between door and plunger that pops it open,the plunger is located at the rearmost centerof the door ,the door striker that rsts against plunger could just be out of adjustment,if you operate the release and see the plunger moving it's ok,adjust the striker a simple little tug towards the plunger is sometimes all it takes
