Everything you need to know about automotive key services, transponders, pricing, and working with AutoKeyMaker.
AutoKeyMaker specializes in originating new keys for vehicles where all keys have been lost or stolen. We can decode your vehicle's lock, cut new keys, and program the transponder on-site at your location — no towing required. Having your VIN number available when you call helps us prepare and provide an accurate estimate before we arrive.
Modern car keys contain a small electronic chip (transponder) embedded in the key head. When you insert the key, the car's immobilizer system reads the chip — if the code doesn't match, the engine won't start even if the mechanical cut is correct. Programming this chip requires specialized equipment and software. This is why automotive key work costs more than a simple hardware store copy, but still far less than a dealer.
When AutoKeyMaker originates new keys for your vehicle, the process typically erases all previously programmed transponder codes from the vehicle's computer memory. This is a security feature — it prevents anyone with an old key from starting the car. The old key may still physically open the door, but the immobilizer will not recognize it. This is expected and by design.
This is entirely your decision based on your comfort level with the situation, the neighborhood, and how long you expect to wait. AutoKeyMaker can enter a locked vehicle if you decide to secure it while waiting — we have the tools and techniques to open most vehicles non-invasively. There's no wrong answer here.
For Toyota and Lexus vehicles where all transponder keys have been lost, some dealers recommend replacing the entire Engine Control Unit (ECU) — an expensive process that can take up to a week. AutoKeyMaker has the equipment to reflash the onboard memory of these vehicles on-site, allowing new keys to be programmed without replacing any hardware. In most cases this saves hundreds of dollars and days of wait time.
We don't publish fixed prices because the cost varies significantly based on your vehicle's year, make, model, security system type, number of keys needed, and your location. Call us at 203-339-1870 and we'll provide an accurate estimate. What we can guarantee: our prices are significantly lower than dealer rates. Payment is cash only, due at time of service. If your vehicle is determined to be non-serviceable after a key creation attempt, the price is reduced by 50%.

This is possible in some cases — call us for details specific to your vehicle. Not all aftermarket key blanks are compatible with all vehicles, and some manufacturers require original equipment keys for programming. We can often advise you on whether a particular blank will work before you purchase it. Using the wrong blank can complicate the process significantly.
Most general locksmiths specialize in doors, safes, and simple mechanical locks. Modern automotive key systems — transponders, immobilizers, rolling codes, proximity keys, push-button start — require specialized training and equipment that most locksmiths don't have. AutoKeyMaker specifically focuses on automotive key technology, which is why we can handle situations that other locksmiths and even some dealers cannot.
