View Full Version : Electric door locks and cold weather
01-25-2004, 08:31 AM
In extremely cold weather the drivers door electric lock ceases functioning. will not work via key fob (this prevents any doors from unlocking since the drivers door must unlock first before the others will respond) or from the door switch (only drivers door will not lock or unlock). When OAT rises locks function properly. I am having Honda service check it out this week but would like to know if any others have had this problem.

Haven't seen or heard of that one. Offhand, I'd check to make certain that the receiver unit that's mounted under the dash is truly seated in it's connector, as maybe--just maybe--with the cold the plastic shrinks a bit and it's not making good connection.
Or, perhaps, your keyfob is the one with the trouble, but since you note that when it's warmer out it works then it's probably not the case (unless you're keeping your keyfob out in the cold).

I've had this happen a couple of times in my '99 EX. I don't think it's the remote control actuator though. I'm pretty sure that it was the door lock itself freezing, as I wasn't able to use the key to open the door, either. Get some lock de-icer and consider some dry lubricant for the lock once Spring finally gets here and outside temp is above freezing.

Some very useful stuff to have is Mercedes Benz lock cylinder grease (Schließzylinderfett). MB part number is A 001 989 26 51 10, and it comes in a small 25ml spray cylinder, with a key-shaped nozzle. Price is about $12, and mine has lasted 4 cars.

Thank-you for the responses. I will try ttempels suggestion about the relay connections, although I installed it myself and made sure that I had it seated properly, it never hurts to check. Also the door will not unlock from the switch on the door either. I am able to open the door easily with the key so I do not think that it is caused by ice in the lock. Thanks for the replies regardless.

I had this issue come up about 3 times when it got REALLY cold here in Detroit. After the E warmed up once started, everything worked as it should again. It was most definitely a WTF moment, that's for sure. I had gotten the E washed the first time the locks didn't work and wonder if water had somehow gotten into the door and froze up. Hard to say really. I am going to mention it to my tech when I take the E in for it's 20K oil change.

Just what happened to me. Car wash, then single digit temps. Perhaps water finds its way into the actuator solenoid....? I never did get my E in for the service techs to look at it and the weather has not been cold enough since to cause the problem again. I would be interested in what your technician has to say if you would not mind posting his response here.

Lock-Ease graphite aerosol has a propellant, and graphite in suspension. It seems to do a good job of flushing out crud / displacing moisture, and leaving a (messy) coating of graphite to lube the door and ignition locks.
I mention the messy part because it will get on your keys the first few times, but DOES IT EVER MAKE THE LOCKS FEEL SMOOTH !!!
I think I got it at a locksmith, or Home Depot, and a tiny (blue =yellow) spray can has lasted me for several vehicles. When a real locksmith overhauls a lock, the last thing he does is put a shot of graphite in there, never OIL / WD-40.

Late this January 2005 in the very cold weather my right door's actuator won't work unless the car's been warmed up. Naturally, at the 30K service, the dealer couldn't make it happen.

I have not had issues with the lock in the cold, but often the door latch itself gets a bit stiff and the door has to be slammed quite hard to make it hold closed.

:twisted: HAD THE SAME PROBLEM WITH MY 2004-EX ELEMENT..CAUSE..WATER GETTING INTO LOCK SWITCH CALLED THE "ACTUATOR"....OF COURSE WHEN COLD IT WON'T WORK-WARM WORKS FINE. WAS REMOVED AND HAD WATER IN IT...REPLACED BOTH DRIVER/PASS SIDE. ALL IS GOOD IN SUBZERO NOW.(JUST VERY CARFULL WHEN I WASH,TRY TO LIMIT SPRAY ON WINDOW AND LOCK AREA). THE "KERMANATOR" IS FINE NOW! 8)
