hello folks,

i purchased an oem keyless remote set from sewell about 4 years ago for my 93 sc400. I replaced the rom chip in the rear panel and it worked intermittently but now for some reason it doesn't work at all. I was wondering if there's something i should check? key-less ecu, fuse, relay? Its a strange problem I've been having. My remote also works on 95.1fm.

Thanks

Does the failure happen with all your keys? If so, that would eliminate the keys as being a problem.

check your wiring, maybe you have a bad ecu, or the transponder is damaged. try flicking the switch under your steering.
