Hey,

I just added a remote to the car, its an evo 8, 2004 japanese model fq300.
I short circuited the pin 1-4 at the OBD port and did the programming procedure.. everything is working fine i push LOCK button all the doors are locking, i push the UNLOCK button all the doors are unlocking.. BUT.. If i lock the car with the remote after 30-40 seconds the car unlocking automatically. If I lock the car from the door's lock, mechanically, all the doors are locking perfectly and don't unclocking back after. Its unlocking back only if i use the remote.

What you thinking guys where i need to search the problem?

Thanks,
Mario

 

Take a look into the driver's side door lock actuator I know when that goes bad some funky stuff happens with the fob locking. There is a few threads with similar problems seach around. I'm also having driver side actuator problems when using fob only locks other 3 doors with fob unlocks all with fob every once in awhile will work correct.

 

I checked that before, its easy to check because on the dashboard it has a light "careful, your door is open" if i open 1 door that light is up, if i close it the light is off on the dash, i checked on this way all the actuators. All working.
Its interesting because all of the door locks are working well, all locking and unlocking perfectly with remote, just I wait around 40 seconds and all the locks are open again.

Thats easy to solve a problem if one door don't open or close because there is the problem But its different from other threads. Here everything is fine and working how its need, just after that time its open again, like it has a timer.
