key fob and tire pressure monitors go out in cold weather The temp got down to 25 last night and this morning the tire pressure monitors and key fob don't work. Is it possible that its related to the cold weather? Its 35 now and I just went back out to my car and both systems still do not work...blah. AND my powersteering pump screams when it gets into the 30's or below. It is quiet if its warm out. It was the coldest night in 2 years (and getting colder as the week goes on..lol). I might just stop driving it for the week..lol.

wish I could help. My tire pressure monitors work and we got down to 19* here last night. The TPM's run off batteries right? Well if it gets cold and your batteries are running low on power the cold will zap the rest of the power out till they warm up.
As for the power steering pump....could be the bearings need to be replaced.

I added one or two ounces of powersteering fluid and now it is fine. I knew it was a little low, but didn't think it would be that big of a deal.
The remote and tire pressure sensors still dont work though
and they worked yesterday..lol.

My front left TPS went out on the roadtrip from Miami to Chicago, right around the same time my display notified me that it was icy out 
It randomly went on and off for the next day and now it won't turn back on.

My front right has been on and off for the last few days and now all 4 dont work..which sucks because I have a tire with a leak in it...it only leaks when sitting up and its random as to how much it leaks in a day. Some days it doesnt leak at all, some days I have to add 10lbs of air.

Yeah the key fob needs to be working to do the tpms reset. I just don't remember if I needed my friend with a tech 2 to get the key fob working or if it came back on its own.

That makes 3 of us!!! I had a post up about this a while ago but nothing worked. Same thing key remote and tire sensors. Mine went out with my car just parked in early october so it has nothing to do with the cold. Also I have a valvestem on one tire that continuously leaked think this could have triggered the loss of the pressure sensors but wtf does it have to do with my remote??? I know if they "reboot" my comp at the local kelly cadi, the dude said its like $118 or something of the sorts. Think that should reset everything cause I'm sick of not beeing able to open and lock my damn doors and especially the fkn trunk. Thanks for not putting a key hole in the trunk or a push button Cadillac! Always fun to have to lower the rear seats, climb in the trunk, and pop the emergency hatch.

The key fob and tpms are linked to the little module in the rear of your headliner. I know because when i swapped from my tan to black interior, i forgot to swap that module and dealt with these same annoying problems. Managed to get my old module back off my old headliner and installed it which solved my problem. Id bet its that module thats being effected by the weather since it controls both the remote fob and tpms.
I however have had my passenger rear tpms sensor turning off every once in awhile but it always comes back on a couple mins later. The other 3 have never gone out on me but I am assuming since the life expectancy on the tpms sensors is 6-7 years, its prob the first to start to going out due to age. Ill prob replace the set when i buy my next set of tires.

Module is a small electrical box that clips into the headliner above the dome light. If I remember correctly, it has 2 wires that plug into it and a small wire that comes out of it to the dome light I believe. Been awhile since I messed with mine. The screw under ur dome light goes through the metal of this module to work as a ground. My car is an 04. I'm not sure if the 05's are different or not but I doubt it.
