“Lost the only key to my Honda on a Sunday night. He showed up, cut and programmed a new key right on the street and explained the price before starting. Fast and honest.”
Questions from Elizabeth
Why should I erase the old keys of a used car?
Because you can't know how many keys were made for the car. Erasing them and reprogramming only yours means no one else can start your vehicle.
Do I need to bring the car anywhere in Elizabeth?
No. We are 100% mobile and do the work wherever the car is parked.
