I am unable to add a 3rd Key. I have 3 good transponder keys. I am able to program only 2 of the keys at a time. All keys are good as I enrolled keys. One key will drop out when programing . States you can do 5 keys.
Maybe the car was a rental car before you or your customer had it , and certain keys and remotes were lost and replacements programmed , so it may already reached the 5 limit after you added the 2 that work.
Thanks for your help The 906 says will delete all keys when I attempt the programing not sure what's the cause is. It enrolles. The last 2 of 3 Key's. I get 5 flash light Like it supposed to. I find it will do this In any order it will do last keys. So all keys are good
What I found out is you have to tell the 906 you replaced the bcm thats the only way I can reprogramming and then hope the RED Security icon is illuminated. Keep key on shut down the 906 Go back and this time say regeistar key
