My keyless entry has been getting worse & worse on my 94 coupe,so today I put in a fresh set of batt.It will not open the doors & once in a while it will lock them as I walk away,tries several diff batt. & still no good.Tried to reset but still busted.How long do these little gadgets work for?after 10 years should I just replace the keyless enrty unit[on my keychain] or could it be something else?What are they worth? :cuss
New fobs are around $160 from the dealership. I have seen them on eBay for around half of that. Ecklers is around $140.
I had a similar problem before with mine as well. Mine wasn't the fob (I replaced the batteries like you did). It actually turned out the car battery wasa going bad. May want to get the battery tested to make sure it is still good. That could be the problem. I have found any time electrical type gremlins pop up that the car battery is on its way out.
