You don't have the key to start the car. This is the most common car key replacement scenario and the most urgent. A mobile locksmith can originate a new key from scratch using your VIN and proof of ownership — no existing key needed. This is also the most expensive option because the locksmith must decode or pull the lock cylinder to create the key from scratch.

Your current key works, but you want a backup before you lose it. Duplicating from an existing key is faster and less expensive than originating from scratch because the locksmith copies the cut pattern directly. If your key has a transponder or smart chip, the spare still needs electronic programming.

See our car key duplication service for spare key pricing and options.

The key turns in the ignition (or the fob buttons work), but the engine will not start. This usually means the transponder chip has lost synchronization with the vehicle’s immobilizer, not that you need a new key. Reprogramming the existing key is faster and cheaper than full replacement.

See our car key programming service to diagnose the issue.

The key blade is physically damaged — snapped in the lock, bent from force, or worn down so the cuts no longer engage properly. A locksmith removes the broken piece (if stuck) and then cuts a new key from the original code. If the key has a transponder chip, the new blade must be paired with the existing chip or a new one programmed.

Call  (407) 255-5714 — we extract broken keys and cut replacements on-site.

Standard metal car keys have no electronic chip and work purely through physical cuts matching the lock cylinder. Common on vehicles manufactured before the mid-1990s and some fleet or utility vehicles. Key Copy By Mo cuts standard car keys on-site in under 5 minutes.

Transponder keys contain a small electronic chip embedded in the plastic head of the key. When you insert the key and turn the ignition, the car’s immobilizer reads the chip’s unique code — if the code does not match, the engine will not start. Most vehicles manufactured after 1998 use transponder keys. Our locksmiths program transponder chips on-site with OEM-level equipment.

Smart keys communicate wirelessly with the vehicle through radio frequency. You carry the key in your pocket or bag, press a button on the door handle to unlock it, and press the start button on the dashboard to start the engine. Smart keys are standard on most vehicles manufactured after 2015 and nearly all luxury brands. Key Copy By Mo programs smart keys for Toyota, Honda, Ford, Nissan, BMW, Mercedes-Benz, Hyundai, Kia, and all other major manufacturers.

Key fobs combine a physical key blade with remote buttons for locking, unlocking, and trunk release. The fob’s remote functions are programmed separately from the key blade’s transponder chip, meaning both components must be correctly paired to the vehicle. We replace and program complete key fob assemblies at your location.

Laser-cut keys use a milled track cut into the center of the key blade rather than traditional edge cuts. The track pattern is more complex and harder to duplicate without professional equipment. Common on luxury vehicles (BMW, Mercedes-Benz, Lexus, Audi) and many Hondas and Fords manufactured after 2010. Our automotive locksmiths carry laser-cutting equipment in every service vehicle.

Switchblade keys fold the key blade into the fob housing and spring open with a button press. The blade and fob electronics are a single unit — if either component fails, the entire assembly may need to be replaced and reprogrammed. Key Copy By Mo replaces switchblade keys for all makes, including Volkswagen, Kia, Hyundai, and Chevrolet.

Hardware stores like Home Depot and Lowe’s can cut standard metal car keys — the kind with no electronic chip. If your vehicle was manufactured after the mid-1990s, it almost certainly uses a transponder, smart key, or key fob that a hardware store cannot program. Buying a key blank online is even riskier: the blank may not match your vehicle’s specifications, and you still need a locksmith or dealer to cut and program it. In most cases, ordering a blank online and then paying a locksmith to cut and program it costs more than having the locksmith supply and program the key in a single visit.

Most car key replacement customers in Orlando save 40–60 percent compared to dealership quotes. A mobile locksmith eliminates the tow bill (if you have no working key), the service appointment wait, and the dealership labor markup. Key Copy By Mo carries the same OEM-grade key blanks and programming equipment the dealer uses — the difference is we bring it to your vehicle instead of making you bring your vehicle to us.
