Let's talk about GM High Security Ignition Cylinders,
These are often found with the Flip style key and fobs in most Passenger cars and SUV's from 2010 and newer, as well as the the Chevrolet and GMC trucks 2014 and newer.
They will one day out of the blue stop working. DO NOT TRY AND FORCE THESE, you may end up like this customer with a broken igniton and require it to be replaced. This opening the first photo the inner cylinder is broken right in half, But if you call me, save a tow bill and costly replacement at a dealer or garage, I can come out to the vehicle, remove it with out drilling it out and repair it for a fraction of the cost from your dealer or garage.
In my second picture you can see the difference between a new ignition wafer and an old worn out one, the tab that follows the groove in the gets worn and thin, when it is worn out like this it doesnt become level in the cylinder to allow it to turn, a simple rebuild and you will be on your way in no time with my service!!!
