About Our Car Key Replacement
Losing your car keys or having them break beyond use can bring your entire day to a halt. Dealerships charge hundreds of dollars for replacement keys and often require you to tow the vehicle to their lot, adding even more expense and waiting time. Nonstop Lock & Key provides on-site car key replacement throughout the St. Louis area, cutting and programming new keys at your location for a fraction of the dealership price.
Our mobile automotive locksmiths carry a comprehensive inventory of key blanks, transponder chips, and programming equipment for most vehicle makes and models on the road today. We can replace standard metal cut keys, transponder chip keys that communicate with your vehicle immobilizer system, high-security sidewinder and laser-cut keys, and remote head keys that combine the key blade with remote buttons.
The process is straightforward. When you call, we verify your vehicle information and confirm we have the correct key blank in stock. We then drive to your location, verify your vehicle ownership through your registration or title, cut the new key to your vehicle specifications, and program the transponder chip or remote functions as needed. Most car key replacements are completed in 30 to 45 minutes on-site.
We work with all major vehicle manufacturers including Ford, Chevrolet, GMC, Toyota, Honda, Nissan, Hyundai, Kia, Dodge, Jeep, Chrysler, BMW, Mercedes-Benz, Volkswagen, Audi, and many more.
