How much does car key replacement cost in the UK?

Most modern car keys have an embedded electronic chip that enables owners to start the engine. And like other car accessories, these electronic parts can break over time due to wear and tear, necessitating a replacement. So, how much does it cost to replace a car key? Expect to pay £66 to £1,200 in the UK. 

What are the average costs of car key replacement in the UK?

Car key replacement costs can vary widely, depending on the location. For instance, car locksmiths in major cities like London and Birmingham charge more due to the high operational costs. As might be expected, prices are lower in rural areas, but since there are fewer car locksmiths in these areas, the lack of competition can drive up the cost. Here’s a breakdown of the average cost of replacing keys per city.

What factors affect the costs of car key replacement?

Let’s find out the factors that affect the total price so you’ll know exactly how much a replacement car key costs. 

Key type and features

Throughout the years, cars have evolved, with various automotive companies creating new and advanced models, so you’ll usually find many types of car keys on the market. Below is a table of how much a new car key costs based on its type and features.  

As shown above, complex key types like transponder and smart keys have higher replacement costs than standard car keys due to their electronic components. Plus, they require special programming to enhance their security and prevent easy copying. 

Car make and model

Auto key replacement prices are based on the car’s make and model. For instance, luxury and high-end brands such as BMW, Lexus, and Mercedes Benz cost more because they have more advanced key technology embedded, such as transponder chips and proximity sensors. 

However, some car models, even within the same brand, can have varying prices because each car has different specifications, with some having the same features as luxury car keys. So, it comes as no surprise that other car brands have a large cost discrepancy, sometimes surpassing the highest car key replacement cost of luxury brands.

Programming requirements

As mentioned, some car keys, transponder and smart ones, require programming to the car’s computer system. They typically require an OBD2 tool, and only a professional from a dealership can help you program them. Note that some cars need a unique PIN code integrated into their internal memory to program the new keys. 

Smart keys for luxury cars cost more than transponder keys because of their complexity. Some of these high-end cars require part removal before key programming, increasing the total cost of auto key replacement. For reference, key programming costs around £30 to £200 in the UK.

Location and time of day

Your location can also factor in the total cost of replacing your car keys. For instance, if you live in the city and lose your car keys, expect the automotive locksmiths in cities to charge more because of the higher demand and cost of living. While costs are generally lower in rural areas, there may be additional travel fees to reach you.  

Aside from the location, it would be best to consider the time of day. Hourly rates for car key replacement during standard business hours range from £43 to £80. Meanwhile, if you need an emergency locksmith service during off-hours, let’s say late at night or during holidays, their rates are higher, with additional call-out fees typically ranging from £80 to £145. 

Labour fees

You’ll also have to consider the labour fees of automotive locksmiths in the total car key replacement price. This can depend on the job’s complexity, so if you have an old manual car and need a standard replacement for traditional mechanical keys, the cost ranges from £50 to £160. 

However, if your keys require complex programming, as with transponder keys, the cost can range from £100 to £250. Meanwhile, car keys for luxury cars are the most expensive, with prices ranging from £200 to £350. 

Warranty or insurance coverage

You may wonder if you can save money through car warranties and insurance. Unfortunately, manufacturer warranties don’t usually cover the cost of replacement car keys because they only focus on mechanical and electrical defects. Accessory replacements such as car keys can only be covered if there’s a manufacturing defect within the car’s locking or ignition system.

Some car insurance policies can cover the cost of stolen car keys. However, if you misplaced or lost your keys, you’ll have to cover the cost of lost car key replacement out of your pocket. For reference, a lost car key replacement in the UK can cost approximately £150 to £372. 

What are some ways to save on car key replacement?

Now that you’ve got a rough idea of how much it is to replace a car key, you are probably wondering if there’s any way to reduce costs. Here are some tips to help you save money on car key replacement. 

Consider a third-party car locksmith 

Car dealerships often have high fees due to brand markups or the amount they charge above the manufacturer’s suggested retail price (MSRP) for popular car models. It’s best to go to a third-party local car locksmith in your area, as they can provide the same quality key car replacement services for a fraction of the cost.

Shop for aftermarket car keys

These are manufactured by third-party companies or independent car manufacturers and are designed to meet or exceed the original equipment’s (OEM) specifications. They are usually available at a fraction of the cost of car dealership keys. Just make sure to buy from trusted suppliers because aftermarket car parts and accessories tend to have compatibility issues. 

Choose a local locksmith

This enables you to save on additional travel costs and call-out fees. Hiring a locksmith in your area also ensures faster turnaround time, which can be advantageous during accidental lockouts or emergencies.

What should you look for in a car locksmith?

Since replacing car keys can be quite pricey, you want to ensure that the auto locksmith you choose is trustworthy. Here’s how:

Certification and specialisation in automotive locksmithing

While there is no government-mandated licensing for car locksmiths in the UK, it is best to choose a locksmith with certification from the Master Locksmiths Association (MLA). The MLA is responsible for holding regular inspections to check a locksmith’s credibility and professionalism.

You should also check if they specialise in automotive locksmithing because locksmiths may have different areas of expertise. 

24/7 availability

It would be great if you could find a locksmith who offers round-the-clock mobile mechanic services in case of emergencies. This way, you’ll feel assured that they can help you if you suddenly get locked out of your car in the middle of nowhere. 

Comprehensive service options

Although car key replacement is mainly the job you need from an automotive locksmith, they could also offer complementary services, such as key-in-locked car retrieval, ignition repair or replacement, key repair, and transponder key programming. Knowing they provide these means that they can handle any car lock-related issue. 

Recover access to your car through Airtasker
