Car Key Replacement & Locksmith Service
Lost your only key, need a spare cut, or your key fob stopped working? Mobile locksmith service cuts and programs most modern keys on the spot.
Losing your only car key, or having a fob that’s stopped working, doesn’t necessarily mean a trip to the dealership. Mobile locksmith service can cut and program most modern keys right where your vehicle is.
Car Key Replacement
Whether your key is lost, stolen, snapped, or simply worn out, mobile key replacement can cut a new key and, for the vast majority of vehicles built in the last two decades, program it to work with your car’s immobilizer system on the spot — no need to have your vehicle towed to a dealership.
Transponder Key Programming
Nearly every vehicle made since the late 1990s uses a transponder key — a key with a small embedded chip that communicates with the car’s immobilizer system. Without the correct chip signal, the engine won’t turn over even if the key blade is cut perfectly and physically turns in the ignition. Programming this chip to recognize your specific vehicle requires specialized equipment, which our mobile locksmith service carries for most common makes and models.
Key Fob Replacement & Programming
Lost or malfunctioning key fobs — for remote lock/unlock, and on many newer vehicles, push-button start — are one of our most common locksmith calls. A replacement fob can typically be programmed to your vehicle on-site, restoring full functionality without a dealer visit.
Spare Key Cutting
Even if your current key works fine, having a mobile locksmith cut a spare on-site is often more convenient than a dealer visit or hardware store key machine, especially for a transponder key that needs programming rather than just cutting.
Broken Key & Ignition Extraction
If a key has snapped off inside the ignition cylinder (rather than a door lock — see our Lockout Service page for that scenario), careful extraction is needed to avoid damaging the ignition mechanism itself, followed by cutting a replacement key.
When You Might Need a Dealer Instead
A small number of newer, high-security vehicles use manufacturer-specific systems that require dealer-level programming equipment beyond what mobile locksmith service carries. Tell dispatch your vehicle’s year, make, and model, and they’ll confirm whether mobile service covers it or advise on next steps if a dealer is needed.
What It Costs
Pricing varies significantly by key type — a basic cut-only key for an older vehicle costs considerably less than a transponder key or smart key fob requiring programming. Ask dispatch for a quote specific to your vehicle’s year, make, and model before scheduling.

Car Key Replacement & Locksmith FAQ
What's the difference between lockout service and key replacement?
Lockout service gets you back into a vehicle when a working key exists somewhere — locked inside, lost nearby, or temporarily inaccessible. Key replacement is for when you don't have a working key at all — it's lost, stolen, badly damaged, or you simply want a spare made. If your key is locked inside your car right now, start with our Car Lockout Service instead; call key replacement if there's no working key to retrieve.
Can you cut and program a key on the spot, or does it need to go to a dealer?
For most vehicles made in the last two decades, mobile locksmith service can cut and program a replacement key or fob on-site, including transponder keys that need to communicate with your car's immobilizer system. Some newer, high-security vehicles or specific manufacturer systems occasionally require dealer-level programming equipment; dispatch can tell you whether your specific make and model is covered by mobile service or needs a dealer visit.
What's a transponder key, and why does it cost more than a basic key?
A transponder key has a small chip inside that communicates with your car's immobilizer system — without the correct chip signal, the engine won't start even with the correctly cut key blade inserted. Nearly all vehicles made after the late 1990s use transponder keys. Programming this chip to your specific vehicle requires specialized equipment, which is why transponder key replacement costs more than a simple cut-only key for an older vehicle.
Do you handle key fob replacement and programming?
Yes — key fob replacement (for remote lock/unlock and, on many newer vehicles, push-button start) is a standard part of our mobile locksmith service, including programming a new or replacement fob to work with your specific vehicle.
