Default Re: How to fix lock/unlock system?

[QUOTE=autostaretx;831063]In the T1N, the documented cycle is that if you press a fob's buttons more than 256 times without the Sprinter "hearing" it, you'll lose sync and that fob won't be acknowledged.
(it's sending a "rolling code", not different frequencies)

People with small children that like to repetitively press buttons have encountered this.

Is there a way to re-sync the fob without taking out the Skreem and sending it in? My only key fob also blinks red and has no effect on the locks! Someone said to disconnect the battery but will this work to re-set the RKE system to the fob?

To the best of my knowledge, that won't perform a resync.
BUT ... there can be many causes for the lock-out, and disconnecting the battery is free.

It certainly can't hurt to try it (and report back).

good luck (and dig up your radio code if you still have the original radio)

An update to this situation (still no solution): The gentleman who installed the aftermarket security system said it will work if I replace the lock mechanisms on the driver and passenger door. He showed me that the inner door handle does not push in and that this is why my locking/unlocking is not working. It moves a little bit when I press lock, but jumps back out to normal position. I tried to clean the mechanism and lube the cable with no luck. Any tips?

I had a similar problem with my passenger door that refused to lock - as soon as the door locked the actuator would unlock the door (it was impossible to lock the door). I ordered a new lock actuator, but once I had the latch out to replace the actuator I cleaned everything wth carb cleaner and lubed it and now that door works perfectly with my 15 year old actuator. So you might try removing the latch and cleaning it until it operates smoothly.

I ran into the same issue with my Remote locks, except on all the 3 original fobs, one is still working. The 2 others seem to have lost sync, which would make sense with dick's comment as the previous owner of my van has 6 kids.....

SOS Diagnostics confirmed to me via email that they can't "re-sync" the fobs, that they are VIN specific to the SKREEM/RKE Module....

Not sure where to go from here. If anyone has experienced that and was able to have the fobs re-sync, I would love to hear the story....

I'm now very nervous to lose my only Remote functional fob.....

I tried cleaning (brake cleaner) but it's not easy to get in all the nooks and crannies of the mechanism. I'm able to get all of the parts moving, nothing is noticeably gunked stuck, but I don't know how smooth it has to operate. Were you able to push the inner handle in without it jumping back out after cleaning?

svaric, are you saying the front doors will power unlock after pressing the lock button on the center console, or after manually pushing in the interior door handle?

The Sprinter's lock controls have this weird programming where if a lock command is issued by any means (center console button, key fob, or manual locking), it will check the status of each door lock, and if one of the doors remains unlocked, it will power unlock all doors. If you immediately re-lock manually, it will lock, unlock, and lock again. This can be triggered by one of the locks physically not moving into locked position, or the circuitry that senses the lock state isn't completing the circuit. It's commonly caused by weak contacts in the rear doors or sliding door. Note that these contacts are not the same switch that activates the dome lights.

If you're physically pushing one of the front door interior handles into the locked position to activate the power locks, and the power locks then immediately unlock all doors, my guess would be that the problem is in the sliding or rear doors, not the front doors.

Yep.

My son picked us up in the 2006 for a family event. I was on the passenger bench. The lock stem in the sliding door appeared bent so I depressed it to check the operation. As I operated the slide door lock mechanically, all the rest of the doors electrically clacked locked at the same time.

I didn't expect that.

Yes. Cleaning and lubricating the passenger door latch / mechanism (after removing it from the door) allowed the handle to stay locked without jumping back out.
