What does lost keys cover actually protect?

Being locked out is frustrating at the best of times, and if your keys have been stolen, your home's security may be at risk until the locks are dealt with. Emergency locksmith call-outs can also be expensive, especially outside normal hours.

Standard home insurance doesn't always help with lost or stolen keys, so the cost can fall to you. Lost keys cover, provided under the Security & Lock Keys benefit, is designed to take the stress and cost out of an eligible lockout, so you can get back inside and secure your home.

How lost keys cover helps

When your keys are lost or stolen, Security & Lock Keys cover is there to help you get back in and keep your home secure.

Lost or stolen keys

Support when your house keys are lost or have been stolen.

Locksmith charges

Help with eligible locksmith call-out and labour charges.

Safe access

Assistance to regain safe access to your property.

Secure your home

Help to protect and secure your home afterwards.

Exact benefits, claim limits and exclusions depend on your plan and policy wording. Always check before you buy.

What's included, and what isn't

Every claim is assessed against your policy terms, chosen plan, excess and claim limits. Here's the general picture on lost keys cover.

Typically included

  • Lost house keys
  • Stolen house keys
  • Eligible locksmith charges
  • Assistance to regain safe access
  • Help to secure and protect your home
  • Unlimited annual claims, £500 (Essential) or £1,000 (Premium) per claim

Not included

  • Any event that is not an emergency
  • General maintenance and routine work
  • Planned lock upgrades or improvements
  • Wear and tear
  • Pre-existing faults
  • Anything specifically excluded under your policy

Cover levels vary by plan. Always refer to the comparison table, the policy Terms & Conditions and the Insurance Product Information Document (IPID) before buying.

A calm checklist for a lockout

  1. Check safely for another way in: a back door or window you know is unlocked. Never force entry or do anything unsafe.
  2. Ask household members or a keyholder: a partner, family member or trusted neighbour may have a spare key.
  3. If your keys were stolen, treat security as urgent: someone may have your address and keys, so getting the locks dealt with matters.
  4. Call us before arranging your own locksmith on 03333 449 559, so we can confirm cover and arrange approved help, unless you need to act immediately for safety.

Frequently asked questions

What is key insurance?

Key insurance, also called key cover insurance, helps with certain costs linked to lost or stolen house keys, subject to your policy terms and limits. For UK homeowners it's usually designed to help if you can't access your home because your keys have been lost or stolen, and may include support with locksmith charges and gaining safe access.

Key cover is often included as part of a wider home emergency plan rather than sold as a standalone policy. Check the policy wording so you understand what's covered, any excess, claim limits and exclusions.

What does lost keys cover include?

Lost keys cover can include help with lost or stolen keys and eligible locksmith charges, depending on the plan you choose. It may help if you need urgent support to access your home or secure the property after losing your house keys.

With Smart Cover, this is provided under the Security & Lock Keys benefit, with an unlimited annual claim limit and a per-claim limit of up to £500 on Essential or £1,000 on Premium, subject to policy terms, conditions, limits and exclusions.

Which plan includes lost keys cover?

Lost keys cover is included with the Smart Home Plus plan, from £12.90 a month. Smart Home Plus is the most complete home emergency plan and also covers boiler, heating, plumbing, electrics, drainage and pest infestation.

The other plans focus on different emergencies and don't include the Security & Lock Keys benefit, so check the comparison table before choosing.

Does home emergency cover include lost keys?

Home emergency cover may include lost keys if your chosen plan includes security and lock key cover. This means you may be able to get help if your house keys are lost or stolen and you need locksmith assistance.

The exact support depends on your policy, the level of cover selected, and whether the issue meets the policy definition of an emergency. Check whether locksmith charges are included and whether any excess or per-claim limit applies.

What is not covered by key cover insurance?

Key cover insurance typically doesn't cover every lock or key-related issue, and exclusions depend on your policy wording. In general, non-emergency issues, routine maintenance, wear and tear, and anything specifically excluded may not be covered.

For example, a planned lock upgrade or general maintenance work wouldn't usually be treated the same way as an urgent lost or stolen keys situation. Read the policy documents so you know what's included, excluded, and what evidence may be needed to claim.

Is it worth getting key cover?

Key cover may be worth considering if you'd like support with eligible locksmith charges after losing your keys or having them stolen, and would prefer not to arrange emergency help entirely on your own.

Whether it's suitable depends on your home, your existing insurance, your budget and the level of cover you need. Compare what's included, the claim limit, any excess and the exclusions before deciding.

What should I do if my keys are stolen?

If your keys are stolen, treat your home's security as a priority, as whoever has them may also know or be able to find your address. Avoid leaving the property unsecured, and consider having the affected locks dealt with promptly.

Contact Smart Cover on 03333 449 559 so we can confirm your cover and arrange approved help, subject to policy terms, conditions and limits. If a crime has taken place, you may also wish to report it to the police.

How do I make a lost keys claim?

Call our helpline on 03333 449 559 and explain what's happened. We'll check the situation against your plan, excess, limits and terms, then arrange an approved locksmith from our nationwide network to attend.

Avoid arranging your own locksmith before speaking to us, unless immediate action is needed for your safety or to secure your home.
