About Transponder City Locksmith

Our Story

Transponder City Locksmith started from simple beginnings as a small mobile locksmith shop. Over time, we became interested in expanding our service offerings as our client base grew. Years ago, cars had very limited security — the keys were mechanical single or double sided keys. From there, VATS chip keys were introduced and then transponder keys. Transponder keys require special programming equipment that we have, so that the car and key can communicate to start the engine.

Now, we have a real walk-in location with several mobile technician vehicles. Our walk-in shop is great because you can drop your car off to get worked on and we’ll call you when its ready. Whether you need a car key, window tinting, car remotes, or car audio — we can install and service your vehicle in the security of our building. Additionally, our fleet of mobile locksmith vans are fully equipped to program key fobs, cut high security car keys, and program remotes.

We would love the opportunity to earn your business and trust. If you live in Cook County Illinois, give us a call even if you have no car keys. We can travel to your car and make you a car key from scratch very fast. We look forward to helping you in your time of need.
