Making lost keys with a chip

Making Lost Keys With a Chip

Losing a key with a built in chip can stop your day instantly. Unlike standard keys, chipped keys must match both the lock and the vehicle or device security system, so a simple metal copy is not enough. We make replacement keys with a chip that start your car and work reliably, even when all original keys are missing.

Our process is designed to be straightforward and transparent. We confirm what type of key you need, cut the blade accurately, and program the chip so it communicates correctly with your immobiliser. The result is a working replacement that feels and functions like your original key.

What A Chipped Key Is And Why It Matters

Most modern vehicle keys contain a transponder chip that sends an identification code to the car. If the code is missing or incorrect, the immobiliser blocks the engine from starting, even if the metal blade turns in the ignition. Some newer keys also include remote buttons or proximity features, which require additional programming steps.

Because security systems vary by make and model, replacing a lost chip key is not a one size fits all job. The correct approach depends on the car year, the key type, and whether you still have a working spare. If you are unsure what you have, a qualified automotive locksmith can identify the key system and confirm the best replacement route.

Our Replacement Process

1. Verify ownership and key type

For security, we ask for proof of ownership and identification before starting work. Next, we confirm the key format, such as transponder key, remote key, or smart key. This helps us choose the correct chip, key shell, and programming method.

2. Cut the key accurately

We cut the metal blade to match your locks, whether it is an ignition key, a door key, or both. Precision matters because a poorly cut blade can damage the lock cylinder or get stuck. If your lock is worn or sticky, we will tell you before cutting so you can avoid repeated failures.

3. Program the chip to your vehicle

Programming pairs the transponder chip with your immobiliser so the car recognises it as authorised. Depending on the system, we may need to connect to the vehicle through diagnostic equipment, follow a specific learning sequence, or add the key through onboard procedures. This is where professional transponder key programming is essential, since the wrong steps can lock out the system or waste time and parts.

4. Test everything before you leave

We test starting, door operation, and any remote functions that apply. If your replacement includes buttons, we confirm lock, unlock, boot, and panic features as applicable. For proximity keys, we check passive entry and push start behavior where supported.

When You Have No Spare Key

All keys lost is common, and it is solvable. In many cases we can create a new key from scratch, then program it to the vehicle. Some vehicles require additional steps, such as erasing lost keys from memory so they can no longer start the car. This improves security, especially if you suspect the key was stolen rather than misplaced.

If the vehicle is locked and you cannot access the interior, we can also help you regain entry safely. A trained provider can perform non destructive entry to reduce the risk of damage to trims, seals, or lock components.

Common Issues We Solve

• Key turns but car will not start due to an unprogrammed or incorrect chip.
• Remote works but engine will not start because the transponder is missing or not learned.
• Worn ignition or door lock causing sticking, hard turning, or inconsistent operation.
• Broken or cracked key shell where the chip must be transferred or replaced.
• Lost key security concerns where old keys should be removed from the vehicle memory.

If your key is snapped in a lock or ignition, do not try to force it out with tools at home. This can push the fragment deeper and damage wafers. A specialist can provide broken key extraction and assess whether the cylinder needs cleaning or repair before the new key is made.

What To Prepare Before You Contact Us

Having a few details ready helps us give accurate guidance and reduce delays. If possible, provide the vehicle make, model, and year, and whether it uses a standard transponder key, remote fob, or smart key. A photo of the remaining key, if you have one, or the key blade profile can also help, but it is not required.

1. Vehicle identification and proof of ownership.
2. Your location and whether the vehicle is accessible.
3. Any symptoms, such as crank no start or immobiliser warning light.
4. Whether any spare keys exist and if they still work.

We will explain what is feasible for your specific vehicle and outline the next steps clearly. If you need assistance urgently, ask about availability and options for rapid response.

Pricing And Timeframes

Costs depend on the type of key, the programming method required, and the number of keys you want created. Some vehicles allow relatively quick pairing, while others require more involved procedures. We aim to provide a clear estimate before work begins, including any additional parts such as remote shells or batteries.

Our goal is to get you moving again with a correctly cut, properly programmed key you can rely on, and we will not leave until it has been tested and confirmed working.
