Hey, i just bought a 90LS400. it only came with one key. This is an old with without alarm buttons. I'm not even sure if it has an alarm. Should I simply go to good guys/circuit city etc., and have them to install an alarm with electric door openers? I think this may be cheaper than the price of a new key IFthere is an existing alarm.

you should have a factory alarm on it already just lock up the car but leave a window down then try to open it from the inside and that should set the alarm off but if you want keyless entry check ebay they sell them for cheap

If you want the remote keys for this vehicle you will have to get a transmitter set. 2 keys preprogrammed to the ROM chip which goes into the keyless entry module. Replacement cost around $350.00-$450.00 depending on your Lexus dealer.

Take care,

Tami

A decent remote/keyless entry costs$200.00 installed at Circuit City. For 150 more I can get Lexus keyless, thanks Tami!
