What Is a Smart Key (And How Is It Different)?
A smart key (often called a proximity key) allows the car to unlock when the fob is nearby and start via a push button — without inserting a blade (vehicle dependent). These keys typically involve:
- remote locking/unlocking
- proximity detection
- immobiliser authorisation so the car can start

Leicester Smart Key Situations We Help With
Lost smart key (no spare)
If you’ve lost the smart key and have no spare, the replacement route depends heavily on the vehicle system. We’ll advise the safest realistic option once we know your make/model/year.

You’ve got one working smart key and want a spare
This is the ideal time to act. Having at least two working smart keys reduces emergency risk and can be more cost-effective than waiting.
- Replacement keys
- Reasons to have a spare
“Key not detected” / intermittent starting
Often a fob battery, worn fob, or internal damage — but sometimes a deeper issue. We’ll advise based on symptoms and vehicle.

Replacement smart key after damage
If the casing is cracked or the fob is unreliable, replacement can restore reliability (vehicle dependent).

Vehicle and key assessment
We’ll confirm your make/model/year and key system, and whether you still have any working keys.
2) Ownership checks (non‑negotiable)
Smart keys are security devices. We require photo ID and proof of ownership/authorisation where possible.

3) Supply and programming (vehicle dependent)
Where possible, we supply the correct smart key solution and complete the necessary programming so the vehicle recognises it.

4) Testing and spare key advice
We verify the key works as expected for your vehicle (unlock/start functions as applicable), and we’ll advise whether getting a second spare key makes sense.

Used Smart Keys and “Cheap Online” Options (Be Careful)
A common trap is buying a used smart key online and assuming it can be reprogrammed. Sometimes that’s possible; often it isn’t (vehicle dependent). We’ll help you avoid wasted spend by advising on compatibility.
Security and Keyless Theft Prevention (Trust-Building Section)
