Question,
I just got a LX450 with no remote, but 5 keys. Did all these cars have remotes when they were built?
Can I buy a remote and program it to my car?
How can I check if my car ever had a remote?
Thanks,
look for a switch-blank labelled security. it should be next to the hazard switch in the console. If there is a microphone in the thing, you likely have the RS3000/RS3200 security system. Sometimes there's a decal on the front door windows as well.
I'd imagine that all Lexus LX450 should have the factory alarm, but I could be wrong.
On my car, a Toyota RS3000 remote programmed in very nicely. Then I had the whole system removed and had a modern remote-starter equipped alarm system installed.
HTH.
