OK thanks

are you there?

I bought the car used and only received 1 key. Is is not the master key. The shop indicated they did not get a master key with the cylinder housing part # XXXX-XXXXX

Is the ignition cylinder the same as the ignition lock cylinder housing (as my invoice from the shop says) part # XXXXX-XXXXX? The shop says it is a Lexus part but did not come with master key shells. If I can get new keys and an ecm from Lexus dose this need to be installed by a Lexus dealer, which is 200 miles away and a $650 tow if I can't get my car started. I talked to a Lexus dealer and he said replacing the cylinder housing should not have messed up the security programming. Any chance the shop missed a step during the cylinder housing install that is triggering the security system. The shop said did not imobilize the security during the replacement of the housing. I read that if the tone ring was not put back on properly, like maybe upside down the security system would not allow the car to start?

Gotta step out for about 1/2 hour. I'll leave this page open and check back for your reply to my question.

Thanks I am having the shop recheck their work. One more question. If during the install of the housing could the shop have somehow triggered the immobliser so that even if the ring was on wrong and the plugs not connected properly I would have to re-key and get a new ecm anyway? This shop, not a lexus shop unfortunately, is saying they are pretty sure that have done the housing install properly, that's why they are telling me to get a tow (they also will tow me to the Boise, ID dealer for $650) and have a new ecm installed. So, I my question is- If during the install of the housing could the shop have somehow triggered the immobliser so that even if the ring was on wrong and the plugs not connected properly I would have to re-key and get a new ecm anyway? Thanks, Steve

Do you mean when the housing is installed incorrectly it will unset the immoblizer? Dose unset the immoblizer mean the car won't start and I need a new ecm? or just that the car won't start untill the installed housing is done correctly?
