Wondering what to do if you’ve lost your car key? Learn how to find a spare, identify your key type, and when to seek expert replacement services.
Look for a Spare Key
Before taking any action, check if you have a spare key available. Many vehicles come with at least one extra key, often kept in a safe place at home or given to a trusted family member. If you share your car with someone else, ask if they have the spare. A spare key can save time and money, as you can use it straight away and avoid the need for a replacement.
If you find it, consider getting a new backup made as soon as possible. Having more than one key is always a good idea in case you lose one again in the future.
Check Your Car Make and Key Type
Different car manufacturers use different types of keys. Some use traditional metal keys, while newer models may have remote fobs or smart keys. It’s important to know which type your car uses because this affects how the key can be replaced.
Some keys include a chip for added security and must be programmed to the car. Write down your car’s make, model, and year. This information will help when you speak to a locksmith or your car dealer. Knowing your key type also helps you avoid scams and ensures you get the correct replacement.

Modern vehicles often use transponder keys or keyless entry systems that add an extra level of protection. These keys communicate with your car using a radio signal and usually require special programming. If you lose a key like this, the replacement process can be more complex and costly.
You may also need to visit an authorised dealer or a specialist with the right tools. It’s also a good idea to keep your car’s key code in a safe place, as it can make the replacement faster. Checking your manual or contacting your car maker’s support team can help you confirm which type of key your vehicle uses.
Contact a Trusted Locksmith or Key Specialist
If no spare key is available, contact a local locksmith or car key specialist. Choose someone with good reviews and experience in dealing with your type of car key. A trusted locksmith can often provide a quicker and cheaper solution than a main dealer. They may be able to cut and programme a new key at your location, which is useful if your car is locked or you’re far from home.
Ask about the costs and what identification they’ll need before starting work. Avoid anyone who won’t give clear information upfront or charges unusually high prices.
Call Your Breakdown or Insurance Provider
If you can’t get help from a locksmith, your next step should be contacting your breakdown cover or car insurance provider. Some policies include lost key cover, which can save you money. They might be able to send someone out to unlock your car or arrange a replacement key.
Have your policy number ready when you call to speed things up. Not all insurance providers include key cover as standard, so check the details of your plan. If it’s not covered, you might still be able to add it for future peace of mind.

It’s also worth checking if your provider offers emergency transport or overnight cover in case you’re stranded. Some plans include extras like hotel stays or travel costs if you’re stuck far from home.
If your key is stolen rather than lost, you’ll likely need a crime reference number from the police before making a claim.
Always ask your insurer what documents they need and what the claim process involves. Keeping digital copies of your documents and storing your insurer’s number on your phone can help if you ever lose your key again.
Reprogram or Replace Locks If Needed
If you believe your lost key could be found and misused, it’s best to reprogram your car or replace the locks. This is especially important if your key had remote access or if your car can be started without inserting a key.
A locksmith or your car’s dealership can help with this process. Reprogramming will stop the old key from working and help protect your car from theft. Although it may cost more, it adds a layer of security. It’s better to be safe than risk someone gaining unauthorised access to your vehicle.
