Yes, yet another remote start problem thread.
I've been searching around the forum and just read a lot of posts about remote start issues but can't find the info Im looking for.
Looking at getting an '05 malibu LS cheap from a friend who sells used cars, It has a factory installed remote start setup (listed in the options on the window sticker); however the the lock/unlock & remote start buttons on the key fob don't work.
The remote trunk release works sometimes when really close, as does the panic button but nothing else no matter how close to the car. There are 2 key fobs for it and they both do the same thing. The power locks work normally from the DS door. No SES light, etc. Everything else works except this.
All of the power lock and remote start options are enabled in the D.I.C.
I've heard such things as the fob module going bad/ maybe a fuse but I would imagine other things wouldn't function if it were a fuse. Has anyone heard of this specific problem? or have more ideas as to what the prob is?
I replaced the battery (cr2032) in the one fob and now it stopped working. Im guessing these have to be programed somehow? (the manual just says to replace the battery, it mentions nothing of reprogramming)
The other still works with the panic button and truck release only.
I double checked the 7.5amp, Remote keyless entry fuse in the trunk and it is good.
When I changed batts on our fobs, Wife's fob stopped working soon afterwards. Found that the solder points on the battery bracket came loose. I soldered them back (really easy if you've ever done any soldering).
15 mins and it was as good as new.
You shouldn't have to reprogram the fobs after a battery change.
You shouldn't need to reprogram the fobs. One thing to check (it happened with mine when I replaced the batteries) is that the metal bracket that holds the battery broke free at the solder points. I resoldered the bracket and the fob worked.
one thing to check (it happened on mine after I replaced the batteries) is the metal cage that holds the battery. The solder points on mine broke free of the circuit board. I resoldered and all was good. You shouldn't need to reprogram after battery change.
J894 - The first time I replaced the battery in one of my FOB's I noticec that the clip that holds the battery to the ckt. board actually came loose from the board. Fortunately I have a good soldering iron and was able to tack it back down and make the connection. On my 2nd FOB I noted that the solder joint was cracked, not completely broken. Therefore when the FOB was snapped back together it made contact and worked intermittantly. By 'reheating' the cracked solder joint I got the 2nd FOB working again. These seem to be very low quality devices...for something that sells for ~$100 + programming.
I had a similar problem with the battery bracket being broken (looking at positive side of battery the right connector was completely out of it solder joint) I reflowed the solder and I have the same results: trunk and panic work, locks do not with the acception of holding down the unlock button and only the drive door unlocking
this is in my 2007 Malibu LT with only 32,500 miles
I had my remotes go bad. Some of the buttons stopped working. I guess its a problem with a lot of the newer GM remotes. After a while the buttons wear down or something. If your lock button doesnt work then your remote start won't work either since you need to lock your car twice with the remote to initiate the remote start feature. I ended up fixing my remote by buying a fix for it at keylessfix.com . Still working great. By the way. If you have any check engine lights on then your remote start is also automatically disabled by the car.
