Trunk won’t lock

The trunk won't lock even though we tried the remote and the key.
Experienced mechanics share their insights in answering this question :
Hello. When you say the trunk won’t lock, I am assuming that the trunk lid will latch closed but you are able to open the trunk after remotely locking the car. If your car is equipped with keyless ignition, be sure not to have the key on you and stand at least ten feet away and retry. If you have keyless ignition, you may need to refer to the owner’s manual for operation of the system. You can try this yourself first. If the trunk still opens, you could have a wiring problem or a control unit that is faulty. Your best bet is to have a certified mechanic, inspect your lock to solve your issue.

The trunk won`t stay close because the car loses the memory setting for the trunk. This problem usually happens after the car battery dies or the battery gets replaced. Pressing the green trunk release button inside the trunk a few times will allow your trunk to close in most cases.
One of the first things you can do if your trunk won`t open is to try it again. In this scenario, the trunk latch may have gotten stuck due to dirt and debris getting stuck on it or from the trunk rubber sticking to the lid itself. This will require more force to open making you think that the lid is stuck.
Find the reset button on the left side of your instrument cluster. Press the reset button and hold it until your display shows “To reset: Press reset button for 3 seconds.” Push the reset button again and hold it in until the display shows the system has been reset.

Trunk won’t open on my car
ANSWER : Go into your control setup in the instrument panel, under user controls, and make sure the trunk did not get turned off in the setup. If it did, then turn all of it back on and the trunk should open. If the system is all on, try pushing down on the trunk lid and push the button to open the lid. You may have something that caught in the latch. If it still will not open, the only thing to do is to try and access the inside latch using a long grab rod or something equivalent to pull the latch release. If you can’t manage to get it open or want a second opinion on this, a certified mechanic can diagnose your trunk problem firsthand and fix it accordingly.

ANSWER : Your central locking system may have been designed with a control module in the circuit. This is a small computer that is responsible for controlling the different functions of a particular system. It is possible that the module for your central locking system may have shorted out internally preventing particular functions from working properly. I would recommend having a certified technician test your central locking module to determine if all of its functions are working properly.

Automatic Trunk open/close feature not working but button lights up. I soldiered broken wires back together – reset?
ANSWER : Hello, thanks for writing in. Most of the time this is caused by a programming issue with the control module. It usually occurs if the module fails or if there is a loss of power. It can also occur if the batter is jumper improperly but most of the time you will have other issues also. If the battery was jumped correctly then I usually start by reprogramming the control module just to see if it will accept the programming. If it will not, then a new module will probably need to be installed and programmed to the vehicle. Not many places have the equipment to do this, so it is usually best left to the dealer where you got your car. I recommend having one of our certified automotive technicians from YourMechanic come to your home or office to inspect, diagnose, and repair the issue for you.

Corsa b locking problem when I lock all the locks don’t lock but start making a noise as if they were trying to
ANSWER : Hello, thank you for writing in. These types of symptoms can be traced back to several different components. The first thing to find out is if all of the doors are having this issue, or if it is just one of them. Test the inside lock button and see if they successfully lock and unlock the doors. If the key fob and the inside controls both do not work, for any of the doors, then you have a module problem. If the driver’s door is the only door effected, you will want to look at the mechanics, as it is likely the linkage or wiring that has failed.
