Have problem with my aftermarket central power lock, the unlock is acting weird, when I press the unlock key on the remote or pull the unlock **** it will immediately lock itself, it happen only for the first 4-5 times you try to unlock, but after several try it will operate normal. What should I check first?

• Power lock in driver side door
• Power lock module
• Remote alarm module

I recently reset the remote alarm module by the module itself but no effect.

Thanks for the advice.

 

Does the same happen if you use the key to unlock the door?

 

yes when i flip the key to unlock then its immediately lock, what i'm doing i stay the key to unlock position longer for about 2-3 seconds, however the lock function is normal.
so now i'm using the remote to lock from outside, then key to unlock.

 

With that bit of info, sounding like the door lock actuator....not sure if the 6th gens are set up like the 5th or not. Redbull has a very nice post (found in the "Common DIY Threads" sticky at the top) on the common issue with the 5th gens......good luck
