Lost your transponder key? We cut and program a new one on-site.
A transponder key looks like a regular key but has an embedded microchip that communicates with your vehicle's immobilizer. Without the chip, the car won't start even with a perfectly cut key. We cut the blade and program the chip on-site in Eastern Connecticut.
Fast 25-Minute Arrival — because we know that when it's an emergency, you need the fastest locksmith near you right now. People in a panic don't have time to wait. We dispatch quickly so you're not left stranded.

Common questions about transponder key replacement
Quick answers to what most callers ask first.
What is a transponder key and why does it cost more than a regular key?
A transponder key has a microchip inside the plastic head. When you insert the key, the chip sends a coded signal to the car's immobilizer. If the signal doesn't match, the car won't start — even with a correctly cut blade. Programming this chip requires specialized equipment, which is why it costs more than a simple metal key.
Can a hardware store cut a transponder key?
They can cut the blade, but they cannot program the chip. A hardware-store-cut transponder key will turn in the lock but the car won't start. We cut and program in one visit.
How much does transponder key replacement cost?
From $119 depending on the make and model. Call (860) 705-1095 for a phone quote.
What vehicles use transponder keys?
Most vehicles manufactured after 1995 use some form of transponder key. This includes virtually all current Toyota, Honda, Ford, Chevy, Nissan, Dodge, Jeep, and most other major brand vehicles.
How long does transponder key programming take?
Typically 20–45 minutes once we arrive. All-keys-lost takes 45–90 minutes due to the additional steps required.
