What Happens If I’ve Lost My Car Keys Entirely?

If you’ve lost your car keys entirely, it’s stressful—but it’s also a situation automotive locksmiths deal with every day. What happens next depends on the vehicle’s make, model, year, and the type of key system it uses. The priority is restoring access and security so the missing keys can no longer be used.

What happens if I’ve lost my car keys entirely?

When car keys are completely lost, an automotive locksmith will first confirm the vehicle details and your authority to access it. Unlike a simple lock-in, lost keys introduce a security risk because there’s no way to know who might find them or where they could be used.

Once authority is confirmed, the locksmith will explain the safest and most practical way to proceed for your specific vehicle before any work begins.

Can a locksmith make a new car key without the original?

In many cases, yes.

Automotive locksmiths can often create a new key even if the original is missing. This may involve decoding the vehicle’s locks, programming a new transponder or remote, and pairing the new key with the vehicle’s immobiliser. The exact process varies by make, model, and year.

For some vehicles, this can be completed on the spot. For others—especially newer or imported models—additional steps or parts may be required. A reputable locksmith will explain what’s possible upfront.

What about modern vehicles and smart keys?

Many modern vehicles use transponder keys, proximity fobs, or push-button start systems. These add complexity, but qualified automotive locksmiths often have specialist equipment to program replacements.

In some cases, dealership involvement may be required. A trustworthy locksmith will tell you if that’s the case rather than attempting unsuitable work.

Will the old keys still work?

Often, locksmiths recommend disabling or reprogramming old keys so they no longer work. This helps restore security if the missing keys are found by someone else.

Whether this is possible depends on the vehicle’s security system. Your locksmith will explain the options and any limitations before proceeding.

How long does it usually take?

Timeframes vary. Some lost-key jobs can be resolved relatively quickly, while others require additional programming, parts, or approvals. A professional locksmith will give you a realistic expectation based on your vehicle, rather than a generic promise.
