Why a regular key copy won't work on modern cars
If any of these describe what you're dealing with right now, this is the service you need. Call with your situation and location - we'll confirm we can help before sending anyone out.
Your hardware store copy won't start the car
You got a copy made but the car won't start? That's because modern cars need the chip inside the key to be recognized. We program the chip so your car's computer trusts the new key.
You only have one working key
If you lose that one key, replacing it from scratch costs 2–3x more than adding a spare now. Getting a programmed spare while you still have a working key is the smart move.
Your key fob buttons stopped working
If your lock/unlock buttons died but the key still starts the car, we can program a new fob with working buttons and pair it to your car's system.
You bought a used car with only one key
Used cars often come with just one key. We add a second programmed key to your car's system and can check if any unknown keys from previous owners are still active.
Describe your situation - we'll confirm the right service and come prepared.

Why a Spare Car Key Needs Programming
If your car was made after the mid-1990s, it almost certainly has a chip inside the key. This chip communicates with your car's computer every time you turn the ignition. A key without a programmed chip will physically turn the lock but the engine won't start. That's why hardware store copies don't work - they copy the shape but not the electronics.
The Smart Move: Get a Spare Before You Need One
Replacing a lost key from scratch (when you have zero working keys) costs significantly more than adding a spare while you still have one. With a working key present, the programming process is faster, simpler, and cheaper. A small investment now prevents a big expense later.

Key Fob & Transponder Programming FAQ
These are the questions people ask most before booking this service. If yours isn't here, call us - we'll answer it directly.
Why can't I just get a copy at the hardware store?
Hardware stores can copy the metal blade, but they can't program the chip inside. Without a programmed chip, your car's computer won't let the engine start - even though the key fits in the ignition.
How much does a programmed spare key cost?
It depends on your car's make, model, and key type. Basic chip keys cost less than smart fobs or push-to-start remotes. Our specialist confirms the exact price on-site before any work starts.
Do I need to have my working key with me?
Yes. We need your working key present so we can access the car and, on some vehicles, use it as part of the programming process. This is a spare key service, not a replacement.
Will adding a spare key mess up my original?
No. Your original key continues to work exactly as it does now. We're adding a new key to your car's approved list, not replacing anything.
How long does the programming take?
Most chip key and fob programming takes 15–30 minutes once we're at your car. The total time from your call depends on our current schedule and travel time.
Need a working spare key?
Tell us your car's year, make, and model. We'll confirm what type of chip key or fob your car uses and send a specialist to program your spare on-site.
