Can You Replace a Car Key Without the Original?
Yes, you absolutely can. While it may seem impossible at first, qualified auto locksmiths are trained and equipped to make a brand-new car key from scratch. Using advanced tools and diagnostic systems, they can decode your lock or ignition and program a new key that works perfectly with your car’s immobiliser and security system.
This service is especially useful in emergencies, such as when your keys are stolen, lost while traveling, or simply misplaced. You don’t need to go back to the dealership and wait days — auto locksmiths in Leicester can often do the job within hours.
What an Auto Locksmith Will Need
To get started with making a new car key, your locksmith will typically ask for:
1. Vehicle Identification Number (VIN)
This is essential for verifying vehicle ownership and accessing key code data. The VIN is usually found on your car’s dashboard near the windscreen or inside the driver’s side door frame.
2. Proof of Ownership
You’ll need to show proof that the vehicle belongs to you. This could be your V5C logbook, vehicle registration, or insurance documents, along with a valid photo ID.
3. Car Make, Model, and Year
Different vehicles use different key technologies — including traditional mechanical keys, transponder keys, remote fobs, and smart keys. Sharing these details allows the locksmith to bring the right tools and blank keys.
Step-by-Step: How a Locksmith Creates a New Car Key Without the Original
Step 1: Vehicle Identification
The locksmith verifies your identity and ensures that you are the legal owner of the vehicle. Once confirmed, they’ll assess your car’s make and model to determine the key type.
Step 2: Lock Decoding or Key Code Extraction
Using specialised lock-picking or decoding tools, the locksmith will analyse the locks or ignition to determine the exact pattern or key code required. Some cars allow for key code retrieval via onboard diagnostics.
Step 3: Key Cutting
Once the code is known, the locksmith uses a laser or electronic key-cutting machine to create a new key. For remote fobs or smart keys, this may include circuit board configuration and battery installation.
Step 4: Key Programming
Most modern cars (post-1995) require keys with transponder chips or remote pairing. Using diagnostic tools, the locksmith will program the new key to sync with your car’s immobiliser and onboard computer.
Step 5: Testing and Finalisation
Once the key is cut and programmed, the locksmith will test it to ensure it starts the car and that all functions (lock/unlock, boot release, etc.) work correctly.
Types of Car Keys That Can Be Replaced Without the Original
1. Traditional Mechanical Keys
These are simple and easy to replicate, usually involving just key cutting without any programming.
2. Transponder Keys
These contain a microchip that must be programmed to your vehicle. Without this programming, the car won’t start.
3. Remote Key Fobs
These not only unlock the doors remotely but also have a transponder. They need both cutting and programming.
4. Smart Keys / Proximity Keys
These require advanced programming tools and sometimes OEM software to pair them with your vehicle’s security system.
How Long Does It Take?
Depending on your car’s make and model, the complexity of the key, and the locksmith’s equipment, replacing a car key without the original can take anywhere from 30 minutes to a few hours. In many cases, mobile auto locksmiths in Leicester can come to your location and provide same-day service.
Cost of Replacing a Car Key Without the Original
1. Make and Model of the Vehicle
Luxury vehicles and newer models may use high-security keys or encrypted programming, which can increase costs.
2. Type of Key
A mechanical key will cost significantly less than a smart key with push-button start.
3. Emergency Services
If you need a key replaced urgently, outside regular business hours, or in a remote area, this may incur an additional fee.
Estimated Costs in Leicester:
- Basic mechanical key: £50–£100
- Transponder key: £100–£180
- Remote fob or smart key: £150–£300
Still, even with the higher-end options, most locksmiths charge far less than main dealerships.
Why Choose an Auto Locksmith Over a Dealership?
1. Faster Service
A dealership might need several days to source and program a new key, while an auto locksmith in Leicester can often do it the same day.
2. On-Site Assistance
Mobile locksmiths come to you — whether you’re at home, work, or stuck roadside.
3. More Affordable
Dealerships usually charge premium rates, especially for newer models. Locksmiths are generally more budget-friendly.
4. 24/7 Emergency Availability
Many local locksmiths are available 24/7, perfect for late-night or weekend emergencies.

If your key was stolen or lost in a public place, consider reprogramming your car’s system or changing the locks for added security.
