Fast and easy - quick turn around time- strait forward- getting to the CAS is a royal pain in the A$$ (Mini you have to tear the complete dash apart and off) but the reward is a car that starts and runs without issue- if you have a mini that kick clicks but doesn’t start and shows the orange Key symbol on the dash you probably have a bad CAS - do you homework rule out the starter and all electrical connections are in working order and scan your vehicle to confirm it’s the CAS - then send it to these guys along with your keys and a week later I had a reprogrammed CAS with keys back- that works flawlessly. Couldn’t be happier. Thank you guys so much- you Rock.
