Hi All, I have a similar problem on my '99 IS200. Drove the car, parked, locked it, then popped the boot on the fob, closed it. A few hours later went to unlock the car on the fob and nothing happened. Got the spare key and still nothing happened when trying to lock or unlock. Unlocked using the key in the door and the alarm when off, I could start the car ok (all the dashboard lights came on briefly) and the alarm stopped after 30s. Phoned the local lexus dealer and since the fob LED is still bright, they confirmed it was the door transmitter for the immobiliser. They said it would be 'several hundred' to replace it, (gulp). I would attempt this job myself but there may be some CPU interface required to reset the immobiliser and pair it to the key fob. Does anyone have a definitive answer on this? How about a part name or number? I did find this page which may list the part but i don't know which one... http://www.toyodiy.com/parts/p_E_2003_LEXUS_IS200~300_GXE10L-AEFVKW_8420.html Anyone know what 'sub key' and 'cut key' are? Where they mention 'double lock' are they talking about the fob having boot open operation? Failing all that then I will have to disable the alarm and i'm sure there is no manual or blog detailing this! If anyone has done it I would appreciate a private email greg.chance@gmail.com (I can email you a pic of my V5 for proof of ownership). Yours, in desperation... dr pek

Hi did you get any joy fixing this problem? I have exactly the same thing go wrong on mine. Cheers!

further investigation may indicate a broken door link: http://en.allexperts.com/q/Lexus-Repair-81...dle-linkage.htm this link may explain the problem: http://en.allexperts.com/q/Lexus-Repair-81...andle-Lexus.htm well it looks as though i've answered my own problem!

Hi, don't know if your going to reply to this as you posted it some time ago. I have exactly the same problem on my '99 IS200 auto, my rear driver side door. It will open from the inside but not the outside, unlocks fine on the fob. I've had a look around the other forums and it seems to be a problem with the Lexus SC also, see: http://www.fixya.com/cars/t1727778-door_open_from_outside with the only helpful advice of 'replace the door handle'. There is another post: http://www.lexusownersclub.co.uk/forum/ind...p;mode=threaded with the same problem from AdamT. This definitely is NOT a child safety feature as I tried switching the child lock on and now i can't open the door from the inside or the outside. Perfect. Any help or advice greatly appreciated. Dr P
