Are lost car keys covered by insurance?
Are lost car keys covered by insurance? It depends on your policy — and critically, on whether you lost or someone stole your keys. Most drivers don’t check until it’s too late — and with replacement costs reaching £200–£600, it’s worth knowing your position before you need it. Most standard comprehensive policies do not automatically cover lost keys, but many include key cover as a standard or optional add-on. Insurers treat stolen keys differently and may cover them under a broader theft provision. Before you assume you’re covered, check your policy schedule — you could pay £200–£600 to replace a modern car key, so find out where you stand before you need to.
Why car key replacement is so expensive
Modern car keys are significantly more complex than the simple metal-cut keys of previous decades. Most vehicles built in the last 15 years use either a remote fob, a transponder key, or a keyless entry system — all of which require specialist programming alongside the physical key cut.
| Key type | Typical replacement cost |
|---|---|
| Basic remote fob (older vehicles) | £100–£200 including programming |
| Transponder key (most common) | £150–£300 including programming |
| Proximity / keyless entry key | £200–£500 depending on manufacturer |
| Premium / luxury vehicle key | £300–£600+ |
| Complete lock replacement (if keys stolen) | £400–£1,000+ to eliminate security risk |
Dealerships are typically more expensive than approved locksmiths — getting a quote from both is worth doing before authorising any work.
Lost keys — are they covered?
Standard comprehensive policies generally do not cover key loss. Loss is not an insured event in the way that theft or accidental damage is. Losing your keys is considered a failure to take reasonable care of your property.
However, many insurers offer key cover as a standard feature or as an optional add-on for £10–£30 per year. Key cover typically covers when you lose your keys or someone steals them, pays for reprogramming, includes a locksmith call-out if you lock yourself out, and may cover lock replacement if someone steals your keys and compromises your vehicle’s security.
Check your policy schedule under personal belongings, motor legal expenses, or additional cover sections. Key cover is sometimes included without drivers realising.

Stolen keys — are they covered?
Stolen keys count as a theft incident. A comprehensive policy is more likely to cover them under its theft provisions, especially if someone steals them during a burglary or takes them directly from you.
If someone steals your keys from your home, your home contents insurance may cover the replacement cost. Your insurer treats the keys as personal property kept at home. This option often works better than claiming on your car insurance, as it helps you protect your motor no-claims discount.
If someone steals your keys and you think the thief knows where your car is parked, contact your insurer immediately. Your insurer may require you to replace the locks as a security condition before they continue to cover your vehicle. This step matters even more for keyless entry vehicles, as thieves often target them using relay theft. To learn what to do next, read what happens if your car is stolen.
Locked keys inside the car — breakdown cover, not insurance
If you’ve locked your keys inside the car, this is a breakdown event rather than an insurance event. It’s covered by breakdown policies under a lock-out provision. Your car insurer won’t cover this unless you have specific key cover that includes locksmith call-outs. Rooster’s breakdown cover includes lock-out assistance from only £2.99 a month — significantly cheaper than the AA or RAC for comparable cover.
Claiming versus using a specialist locksmith
If you have key cover but your excess is close to the replacement cost, consider going directly to an auto locksmith. Do this before claiming. For older or mid-range vehicles, a specialist locksmith may cut and programme a replacement key for £100–£200. This is potentially below your excess and with no NCD impact. For newer vehicles on a high trim, claiming is usually the right call.
Always try an automotive locksmith before the dealer. Dealer prices are typically 30–50% higher than a locksmith for the same work, and a reputable auto locksmith is fully capable of programming keys for all major manufacturers.
