baught my 92 sc300 about a month ago, and now the keyless entry doesnt seem to be working. the first week it worked fine but had very low signal i would have to stand next to the vehicle enable for it to work. so i thought the battery was low and would have to be replaced soon. just a couple days ago it stopped working and i thought okay time to get a new battery. i went to walmart and replaced the battery went back to my car to test it out, nothing happend maybe the battery was low? the walmart lady generously tested out the battery and the voltage test were good on both the new one and old. yes i checked the keyless entry botton below the steering wheel. ive search on cl and tried the ignition lock/unlock trick to no avail. like i said before it had low signal at first and now nothing its not the same without the keyless entry option. please if someone can help me solve this matter id greatly appreciate it.

 

you're talking about some electronics that are used regularly and are at least 14 years old...everything has a life expectancy.
