Hey guys, i just picked up a 06' IS350.

When I try to lock the doors, it locks then unlocks by itself... Some say its the actuator but im not sure?

Thanks.

 

My first thought is that a spare key fob is inside the car. have you checked the console, glove box, under seats? Of course, this would involve all of the doors locking and unlocking at the same time.

 

I don't think this is it. If you push the door lock button on the door handle, and the other fob is in the car, the doors won't lock at all--you will get an extended beep. IIRC, if you actually press the lock button on the key fob, the car will still lock even if the other fob is in the car.

 

No, the spare is in my house.

When I push the lock in it feels like a spring, and it just unlocks again...

 

Does it lock if you manually lock it? From the inside?

 

Nope, when I manually lock it, it would go back to the unlock position

 

All the symptons of the key FOB inside the car. It does not matter if you lock it with remote or manually, car will not lock. However, if it's the passenger only, and you also said spare key fob is in the house, it may be the sensor that detects key FOB went bad. ???
