Lost Lexus Is250 Se Key

[Andre28]

Hi,

Just wondering whether anyone could shed some light on this issue.

I recently lost the only key I had for my 57 plate Lexus IS250 SE. I ordered a replacement and have had a locksmith and automotive engineer try to program this into the car with no success.

I've spoken to Lexus dealers and head office and they are saying that the only way to get around this issue is to change 2 x ECU's, all locks and buy 2 new keys. The quotes for this work have varied between £3000 and £1470 which seems incredibly strange and even at the lower price seems extortionate for merely losing a key.

Does anyone know any other more cost effective ways this problem?

Any help will be much appreciated!

Thank you

Hello and welcome to the LOC.

Sorry to hear about your problem.

New keys can be programmed from the original master key but without this you are generally at the mercy of Lexus dealers.

Security systems on modern cars are very sophisticated and need to be, the 2 ECUs I would imagine are for the remote locking and immobiliser systems.

Apart from obtaining a complete lock,key and ECU set from a breaker it may have to be the lower of the 2 quotes.

Moral of the story, always have a spare key cut and programmed before you lose the original.
