Yesterday, my second car was stolen and inside i have my RX8 key.

the problem is that the thieves know where i live and if someday comes again and see my RX8 outside knows for what car was the stolen keys with mazda logo.

My question is, can i change my inmobilizer, ecu and my other Key code to make inservible the stolen key?

how much could this be?

 

Easiest way would be the dealer....They can remove key codes..just take you good keys and they can remove all the others from the immobilizer.....

You might be able to do it if you have 2 coded keys...but I`m not sure...I know that you can do it with the remotes...not sure about the keys
