Door does not stay closed. The plastic striker does not stay engaged.

remove door panel to inspect linkage in extreme cold and age the clips/connectors break or pop off also if greased can thicken like a putty and also not allow proper working

It won't lock unless the brain knows the trunk is closed. One way of telling the brain the latch is engaged is by a switch buried in the latch that is pressed when the striker is fully engaged.

A worn/maladjusted striker, worn latch, broken switch or wiring are possible causes...

Striker bolt

Hi Elaine I want you to check 2 things the striker mounted on the body may be loose and moving inwards when you close your door and the door does not catch all the way leaving the door lock in the open position / or the plastic sleeve is missing on it ==if that's ok then go to the actual door lock itself and check it with a screw driver by pushing the lock jaws closed and pulling the door handle to see if it release's spray it with silicone spray/ PB blaster /WD-40 or any lubricant you have handy I really think the striker may have loosened and this is your problem but the actual door lock could have failed you say it works then it doesn't so that makes me feel that the striker has moved also check the door handles to make sure they are not stuck in the applied open position lubricant will help here also here's a couple of photo's for you
<<<<<<<<<
check for the sleeve shown here<<< and check that the nut is tight and that the striker is not placed to far inward that the door lock can not close on it if it is to far in it will grab sometimes and not all the time and the door will be open look for metal scraping marks where it is located if it moved you will see these and also the original marks on the door post where it was originally installed
open the handle and spray lubricant in to make sure the handle is not staying stuck in the open position

spray the handle through the opening when you pull the lever to make sure that it is not staying in the open position
<<<<<<<<<<<< check the lock jaws by pushing with the screw driver and pulling the door handle to observe the lock function and lubricate here<<<<<<<< I the lock is not functioning you have to get a new one I hope this helped you out Good Luck

this could be the door striker plastic has broken off this is the post sticking out of the frame when you close the door the lock closes around the striker to keep the door closed this striker could also have moved slightly from opening/closing the door thousands of times try this open your windows get out close all doors set the alarm wait a minute then try to lightly move the door/s in and out by grabbing the door at the rear part where the door locks to the frame where the striker is if it has any play in it the connection will break and this will make the alarm think the door has opened and the alarm will sound getting the door to close tighter will stop it from happening this is also true for the trunk if you press down on the trunk or your able to pull up on it a little the same thing will happen its loose and will trigger the alarm if this is not the problem I would then go to the door pin switches that turn the lights on/off when the door is opened/closed especially if the alarm was aftermarket installed but you can be sure the alarm thinks that something is opened and the door/trunk/hood are the only places that they are

well, look and see if the striker has slipped back, then, look at the latch, it might be engaged if it is, stick a screw driver in it and pull the handle to release it using the screw driver as the striker.

Hi! Do you mean that when you push the door to close it won't engage? If this is the case, please get a philips screw driver and slide it to the door grabber to rotate. It may be stuck causing it not to engage on the door striker. Hope this helps and thank you for using FIxYa!

You don't state the exact model but on every oven I've ever fixed this problem on it's a broken door striker catch. Depending on your model, the catch will either be in the oven door or in the oven body; usually they're straightforward to replace but on older ovens spares can be almost as rare as dodo ****. Usually what breaks is a hardened tempered metal spring, so when they're not available as spares I can usually visit a local spring making company and get someone to make one up as a one-off using the fragments of the old one as a pattern. After the catch has been replaced the striker itself (usually a specially shaped pin) may need to be adjusted to engage correctly once more. Undoing the lock nut and screwing it in and out adjusts the depth, and is done after the striker catch has been adjusted side to side or up and down to meet the centre of the striker.

The door latch could be closed, in other words, the door thinks it shut into the striker. Take and hold the door handle open, like your trying to open the door, hold the handle out or up and at the same time open the latch, it may be stuck or closed...If that's not it, you may have to re-align the latch to the striker, the striker will come loose with a torx bit. Loosen it up, and move it around and re tighten, it's a trial and error deal, just keep trying different positions until if works right...

hello first thing to check is were the box mounts at the bottom of the door hinge assembly undo the screws you should be able to lift the door enough to release the lock inside goodluck
