New strange effect, sometimes after I spent the car and turned of the key the door lock sistem doesn't open. The handles doesn't functiin and only closing and opening with the key the car opens and let me get out.

Any idea? Low battery of the keys?

Some people have gotten immediate relief by doing a hard reset: at the battery, in the trunk, remove The negative cable from the battery, with a 10 mm wrench, and touch it to the positive terminal. This drains all the capacitors, and has worked for many issues.

Other possibilities: bad control switch at the driver side, bad security and locking control module, bad battery.

 

Don't forget to remove the positive cable from the battery before touching them together as well.

 

That is really not necessary.

 

It's mandatory that you remove both cables from the battery before touching them together. The way you mentioned the procedure was that you remove the negative cable and touch it to the positive. You didn't mention anything about removing the positive cable. Unless you want the original poster to this thread to have a light show, how was my statement not necessary? Safety is the number one priority when it comes to virtually anything.

 

That is really not necessary!!! Energy must flow from a source -- the battery -- to an earth (ground): there is no source at the positive terminal other than the loaded capacitors. Basic stuff!!!

Just to double check (it is repeatable): I just touched my negative cable to the positive terminal -- no light show.

 

Lubrication.
It can also be due to sent locks now that we have colder weather, the lubrication is stiffer. The door handles actuate via a cable to the locks that cause a switch to be tripped that turns on the lock motor to open the door.
Some have had luck spraying wd40 copiously into the lock. I removed the lock looking for the problem, but found it just needed lubrication.

 

Hmm, have you seen the movie "Christine".

 

As JHartz has stated, it is not necessary to remove the positive (+) battery terminal to reset the computers. Removing the negative cable from the battery removes 'active' voltage from the system, the only remaining energy is in ROM's and capacitors. Touching the negative cable to the positive terminal allows those ROM's and capacitors to discharge and WILL NOT cause any light show, sparking or damage.


I've done this many, many times. The only downside for me was the loss of the radio preset memory on my aftermarket radio.....not really a major issue.


My car had locked me in at one point and it turned out to be the door lock actuator...essentially a solenoid. I got our by removing the door card and breaking the little plastic loop on the solenoid. The door handles and key operated lock worked normally after that worked. I hope that isn't your problem, changing that solenoid was a bit tough...
