Beg to differ Lyn

Smartlock and Smartshield are NOT the same thing:

"'Smartshield' is an enhanced version of the Smartlock vehicle immobilisation system it replaces. The most significant upgrade to the system is the addition of a transponder to the ignition key. The transponder 'talks' to the vehicle's electrical system when the ignition is switched on, the management system will not start the car unless the correct signal is received. The signal is an encrypted rolling code that cannot be duplicated."

As I have been told when having my own rewiring overhauled, the smartshield system is reliant upon signals from the key itself, whilst smartlock does not.

I'm no expert, but an auto tech would far prefer working on a smartlock system than a smartshield one.
