Key fob wont lock or unlock doors but will open them

Could be your driver door lock mechanism that is going bad , since the other door are working, it cannot be the fob. I would try to change the driver side door latch mechanism.

Have the key fob reprogrammed by the dealer first and see if that fixes the issue.

if the key does not turn the lock spray it out with wd 40 run key in and out of lock few times.because everyone uses remotes to open their cars the waffers in the door locks get coroded and wont fall in proper place when key is inserted.give it good cleaning and see if it will unlock

you need to reprogram keys with the module. there could be a problem with the module though , you need to check it out

Why not take mit back to the place that repaired it and ask them to fix it properly?

if your unlocking the doors with a key and the engine is starting it wont have a key fob,if your opening the doors with the key and the alarms going off and it wont start then it will have a key fob

get in your car close door hit the unlock button then put key in the ignition cycle the key from off to on (STOP BEFORE START POSITION) cycle key off to on 7 times after the 7th trime the doors should lock the unlock automatically that means u are in trainning mode hit the unlock button on key fob. the key fob should now work if it doesn't then try changing batt

the key has lost its code. open the doors manually and use the central locking button inside the car. hold it down and keep pressing your key fob. this should re code the key

Try pushing the unlock button twice.
