Lost Car Keys ?
Losing your car key can turn a simple day into an unexpected headache. Whether it disappeared while shopping, slipped out during a walk, or was accidentally misplaced at home, being stranded without a key is stressful. Unlock Cars Door provides fast, nationwide lost car key replacement services for all types of vehicles. Our mobile technicians come directly to your location, cut new keys on-site, and program transponder chips, remotes, and smart fobs so you can get back on the road quickly and safely—without towing your car to a dealership.
What Is Lost Car Key Replacement?
Lost car key replacement is the process of creating a new working key for your vehicle when your original key is missing. Unlike simple key duplication, replacement often requires both cutting a new key and programming the electronic components inside it. Modern vehicles use transponders, chips, remotes, and smart fobs, so a professional technician with the right equipment is usually required to generate a fully functional key.
Types of Car Keys We Replace
- Traditional metal keys: Basic keys used in older vehicles.
- Transponder keys: Keys with RFID chips that communicate with your immobilizer.
- Remote head keys: A remote and key combined into one unit.
- Smart keys / proximity fobs: Used for push-to-start vehicles.
- FOBIK keys: Popular on Chrysler, Dodge, Jeep vehicles.
- Laser-cut keys: High-security “sidewinder” keys used on many modern cars.
All replacements are done on-site, saving you time and avoiding expensive dealership towing fees.
How the Lost Key Replacement Process Works
Getting a new key is simple when handled by a professional. Our technicians follow a structured process to ensure the new key works perfectly with your car:
- We verify your vehicle ownership for security.
- We identify your car’s key type and security system.
- We cut a new key to factory specifications.
- We program the transponder, remote, or smart fob if needed.
- We test everything to ensure full functionality.
Most new keys can be made within 30–60 minutes after the technician arrives.
Lost Key vs Locked-In Key
If you lost your key entirely, you will need a replacement. But if you think it may be inside the car, you might only need a Car lockout service. A technician can unlock the vehicle safely and check if the key is inside. If the key remains missing, we can still make a new one on the spot.
How Much Does Lost Car Key Replacement Cost?
The cost depends on your vehicle model, key type, and programming requirements. Smart keys and high-security keys typically cost more due to their advanced electronics. Below is a general price guide for key replacement services.
