okay, i need ALL MY "IS" BROTHER AND SISTER here, to help me solve my problem. any reach, any links, any contacts, any helps, will be graceful. okay look so.. im in minnesota. i lost the device in the key. which cant start up the car without it. (i guess by now it need the device) so i went to the dealership, and ask if i can get a set of new keys or so. reprogram this and that.. plan A, keys from them about 200. reprogram the keys to car 60. plan B, if it doesnt work, they said, since the device is gone, they might have to reprogram the ecu too. but, is there any other option out there then this? come guys i really need your help... thanks

 

Talk to a locksmith most of them do car keys and they are for the most party very helpful

 

if you have a 2001 model and lost your master keys you are screwed. This year has an ECU that cannot be flashed. Meaning you will need a new ECU with master keys either from ebay or the dealer

Now if you have 02-05 is300 then you can buy a key off ebay for $75 and take it to an auto locksmith (not the dealer) and he can flash it for you OR make you a new one from the Valey key.

Hope this helps, ask away if you need more info

 

well try. thanks!

 

kinna like what the dealer said. i will try to ask around more before doing something like that. okay thanks....

 

If its the Valet key you have (no buttons) dasn't open glove box or trunk. Than instead of getting new computer you buy a security system with remote start and door button. Problem solved and no more master key!

P.S. Take that Valet key to the locksmith and he can cut it easy to open glove box and trunk. I think with out even looking at the car

 

actually, that how i travel now. yes with auto start. but i kinna want a master key too. just in case.
