well my keyless entry is officially non-functional. it was acting up for a few months; as in sometimes it would unlock/lock the doors, and sometimes it wouldnt. its annoying cuz everytime i have to get in my car and unlock it with the key, the alarm starts to go off until i start the car!!!

when it first stopped working two days ago, i thought, ok no big deal, ill just go up to autozone and get a new battery for it. when i got to autozone, they had this neat little thing that tests the battery in you FOB, so i tested mine and it worked. i said hmm, i guess ill have to go to the dealership sometime next week.. well today, i talked to a friend of mine, and he said, "just try buying a new battery anyways, you never know". so i went back to autozone, spent 5 bux on a damn battery, and sure enough, it still doesnt work.

has anyone else had this happen to them? what do you think it could be if it isnt the batter in the FOB?

p.s. im outta warrenty cuz im at 43,000 so this wont be covered under warrenty!!!! which means ill prolly get raped when i go to the stealership.

 

both don't work?

 

i bought the car used so i only got one FOB, all i got was the extra key....

 

Happened to me the battery holder thing came in soldered from the motherboard in it

 

so what did u end up having to do?

 

I always wonder why the dealership does that with used cars. Im pretty sure the previous owner didn't want to keep the other fob as a souvenir.

 

well my frist car was a used 2002 ranger xlt, i got both FOB's with that one. but only gave one back since the guy who sold me my cobalt pissed me off.

bump...

 

Not sure either. We have a lot of them leftover from used cars. The dumbest part is that they'll still have the car in the system and wrote up for an inspection. So, that puts me or any other tech in the parking lot wandering around and wondering what happened to the car while pressing the panic button. It's happened to me at least 4 times within the past month. "Oh, oh yeah! We sold that car over the weekend."

At that point you just tell them to DIAF.

 

try unpluggin the battery on your car for bout 15 seconds and that should reset it.. i had the same problem outta mine bout 2 months ago and after i disconnected the battery it started workin again..

 

Could be what the last guy said, or it could be the receiver in the car, or it could be the BCM. When my BCM went (the first time ), the fobs got weaker and weaker until they completely stopped working altogether.

 

ok well what did u end up doin alleycat? did u just take the car into the dealership and they fixed it for you? im guessing if they fixed it for you it was covered under your warrenty for you, but do you have any idea how much it did cost?

 

bump....

 

my key fobs dont work neither one of them and it sucks i need to take it to the dealership to get it fixed

 

im right with ya. ill be goin on tuesday and finding out what they say. im a bit worried tough since my warrenty is up so it wont be covered. hopefully it isnt rediculously expensive....

 

My keyless entry is going out too. Figures my warranty JUST expired.

 

i still have my warrenty thankfully for anothe 6,000 miles so yeah im gonna go tomorrow let me know what they say about yours thanks

 

but at autozone it tested alright.....

my guess it would be the remote control door lock reciever (rcdlr) my moms trailblazer has that problem so i have to find one =\ sorry but i think your **** out of luck.

if its the rcdlr, i dont know where it is on the cobalt but on a impala it pays 2.2 warranty so they may charge you less

p.s. get some lube

 

I have this problem randomly and so do many other members on here.

My problem was: trying to unlock or lock the doors. Sometimes the drivers side door would not unlock or lock even though you can hear the internals in the door working. The passenger side lock always works without fail.

Solution: Many of us have discovered that if you press the lock then unlock buttons back-n-forth for 4 or 5 times it will all of a sudden magically work again.

I'm not sure what causes this issue but it's an easy fix.

Another weird issue that crops up sometimes is the cruise control will become unavailabe every once in a while. I go to set my cruise and it won't do anything. That fix is to disconnect the battery for 15 minutes.

 

bump...neone have any updates on this? i didnt get a chance to go to the dealership on tuesday, so ill be goin on thursday.

 

have you tried this?

Solution: Many of us have discovered that if you press the lock then unlock buttons back-n-forth for 4 or 5 times it will all of a sudden magically work again.

 

yea i tried the lock key thing. it didnt work. as long as nothing comes up, im planning on going to the dealership tomorrow afternoon after i get off of work. so we'll see how much they want to charge me to fix it.

edit: im wondering if me going to get an aftermarket automatic car starter would solve this problem... because if im right, they have to program that auto-starter FOB so that it will work with your car... ne1 have ne idea if that might work?

 

well if your car is still under warranty then the dealership should fix it for free. right?

but yeah, a remote start i would think should resolve the issue. if you want to be sure you should call a local remote start install shop to find out.

edit: i have a number to a place here in pittsburgh if you want to call them to ask...

 

well pittsburgh wouldnt work too well seeing as how i live close to detroit, michigan. lol but i know of a few different places in my area that do auto-starter installs. i could prolly just call up a best buy to since they do all that stuff too.

and im outta warrenty (im at 43,000 miles), so it wouldnt be covered. HOWEVER, when i was under warrenty, this same problem happened (around 33,000 miles) and they did fix it for me then. so i could use the whole "you didnt do it right the first time" approach if they want to rape me on this.

 

try it, theres no harm in trying. if it doesnt work, get ready to pay ALOT of money. it cost my cousin 470$ for a new keyfob for her limited edition mx5. and it wasnt even the fancy keyless unlock/entry/starter fob, just the regular kind. but it wasnt under warranty.

 

true, prices might be different up there.

you can try and pull that card but i doubt it'll get you anywhere. try it thou. worse thing they are gonig to say is sorry we can't help you.
