Hey there, the key registration not being recognized by the immobiliser is generally not a huge issue. It's cause by 1 of 3 things in almost every situation.
1. the key registration has been lost and will need to be re-registered by a dealer or mobile locksmith $100
2. The immobiliser on the ignition cylinder has failed and cannot read the key RFID and will need replaced $250
3. The key is bad and will need replaced and re-registered $150
If you need further assistance let me know, if not just be sure to leave a kind rating so the site credits me for my time.
Hey there, because the immobiliser is involved there is not an easy way to check them without a scan tool here. You need an advanced level scan tool with registration capabilities. I know of noone but dealers and mobile locksmiths with that capability.
If you need further assistance just let me know, if not please be sure to leave a kind rating so the site credits me for my time.
