Door lock push button not working, reset lock at top of lock box works for a day and then buttons won't work.

it maybe the BCM may have a problem or needs to be reset.

What kind of vehicle is it?

Hi,
Saw your thread on the Mustang forum...It'll get fixed there.

To make the keys light up when you want to enter your code, you have to push the lock button on the keypad first. If the keypad light never comes on, open the door and manually lock the interior lock, then press the keypad lock button. The above instructions should then work.

Good luck--and please provide feedback if this helps!

Hi

F9 is a door lock error and to solve this issue you can hold the light switch for 15 seconds, this will reset the control. If it won't work then hold the light switch in and set the unit to clean and after a minute press cancel to cancel the clean cycle. If still it won't work then the door lock assembly should be replaced. Hope this helps...please post back for further assistance.

I think this is an easier way to program. Press and hold the button on the remote and then press and immediately release the smart/learn button on the rear of the motor unit. Do this for each remote you have.

fuse 56 and 57 control central locking,the issue is caused by surges typically in the front door lock actuators, normally at a dealer they would replace fuse 56 and 57 with a 20a mini fuse and if still occuring repl the door lock(s) that dont work or typically both front, first replace fuse 56 and 57 with 20a fuses as were too small from factory and than operate ten to 15 times, if it doesnt work at first dont panic,let the car go to sleep which takes about 16 min and than try again this problem has nothing to do with the key fob or the lock unlock button inside,also the fuses are located behind the glove box just rere the access panel and they are found at lower left section

Try taking the top of the machine off and checking all of the electrical connections, including the one to the door lock. I have to do this about once a month with my machine and it seems to work.

The F90 fault indicates that the maximum time allowed for oven door unlock was exceeded. The control attempted to unlock the door. The door lock motor or mechanism failed to unlock the door within the maximum amount of time it is allowed to be energized by the control board.

It is unlikely that you will be able to reset this fault code. You can try to completely disconnect electrical power and leave it off for 5 minutes. After reconnecting power, the fault code will probably reappear since the control will still detect that the oven door is locked. The only way to clear the fault code is to disassemble the range and repair or reset the oven door lock assembly. You will need a service technician to complete this repair.
