Seat Key Blanks We Cut
Seat uses Volkswagen group key blades, so the right blank depends on the age of the car.
HU66. Used on a wide range of Seat models, including the Ibiza, Leon, Altea, Alhambra, Toledo, Exeo, Arosa, Mii, Cordoba and Inca.
HU162. The newer blade used on the latest Ibiza and Leon, the Ateca, Tarraco, Toledo and Cupra models.
VO-AH. Listed for older Cordoba, Ibiza, Inca and Toledo models.
Most Seat keys today are remote flip keys, and some newer models with KESSY keyless entry use smart keys. The full table of Seat models, years and key blanks is further down this page. It comes from our trade supplier application list, which is correct at the time of writing but may not be exhaustive.

Seat Key Programming
Every modern Seat uses a transponder key that talks to the immobiliser. A new key is cut to your locks and then programmed before the engine will start.
Seat uses Volkswagen group immobiliser systems, and our technicians carry the programming equipment for them. We programme flip keys and KESSY smart keys at your location, and remove lost keys from the car.

Lost Seat Car Keys
Losing every key to your Seat is a stressful problem, but it is one we solve all the time. You do not need the original key. Our technician cuts a new key to your lock, programmes it to the immobiliser and makes sure the lost keys can no longer start the car.
A dealer will usually need the vehicle recovered to their site, then order a key and book a time. We come to your location and get you back on the road, often in a single visit.
Have your V5C logbook and some ID ready when we arrive. We always check that the person asking for a key has the right to the vehicle. It protects you and it protects the next customer.

Seat Car Key Replacement, Remotes and Fobs
Car key replacement for Seat vehicles is at the heart of what we do. Our auto locksmith cuts the car key, programmes it and tests it at the car, whether you need a single car key or a full set. An auto locksmith comes to you, so car key replacement is often faster and better value than a dealer visit.
Help for Lost, Broken and Duplicate Keys
Our mobile technician is a vehicle specialist who deals with lost keys, broken keys and duplicate keys every day. Lost keys are replaced and removed from the car. Broken keys and remotes are repaired or replaced. Duplicate keys and remote fobs are made on site. For emergency assistance with entry, the technician will unlock the door without damage and get you access.
When the Remote Stops Working
A remote fob that will not lock or unlock the door is a common fault. The technician tests the remote, fits a new battery or programmes a new fob, and checks every door responds. A lost remote is removed from the vehicle so it cannot unlock the car.

Common Seat Key Problems
Flip Key Blade Will Not Stay Open
Volkswagen group flip keys wear at the hinge. We can replace the blade and mechanism and keep your electronics.
Remote Not Locking
If a new battery does not help, the remote may need reprogramming or replacing. We can do either on site.
KESSY Key Not Detected
On keyless models, a key not detected message can mean a flat battery or a faulty key. We can test and replace it.

Seat Lock Problems and Lock Service Across Essex
Most key problems have a lock side to them. A tired key wears the locks it turns, and stiff locks wear a new key quickly. That is why our Essex auto locksmith team looks at the locks on your Seat, not just the key.
We will tell you plainly if a lock needs a service, a repair or a replacement part, and we always quote before we touch it.
Broken Keys
A key that snaps in the door or the ignition can be removed by our auto locksmith without damage to the lock. A replacement key can then be cut and programmed on site.
Forced Locks
After a break in attempt, the locks on a vehicle can be left damaged. We restore access, check every lock and recommend a repair or replacement where needed.
Locks We Can Look At
- Door locks
- Boot and tailgate locks
- Ignition and steering locks
- Central locking that locks or unlocks only some doors
- Van locks and high security locks
A general locksmith works on houses. A vehicle locksmith works on car locks, steering locks and key electronics, and carries the tools to open locks without damage. We are vehicle locksmiths only.

How Much Does a Seat Key Cost?
Every Seat is different, so we price each job on its details: model, year, key type and whether you have a working key already. What does not change is how we price. There is no call out fee, no hidden extra and a quote before we start work.
Dealer prices for Seat keys can be high, and you often wait days for the key to arrive. We offer the same quality of work at a fairer price, with the job done at your location.
Ring us with your registration and we will give you a price on the phone.
Car keys for a Seat vary in cost. A basic car key, a remote car key and a smart car key are all priced differently, and replacement keys after a total loss take more work than a spare. Whatever the job, the cost is agreed on the phone first, so the car key service you get has no surprises.
Good car keys are part of good car security. When a car key is lost, we replace it and delete the lost key from the car, so the vehicle stays secure. That service is available across every area we cover, for cars and vans alike.

Emergency Seat Lockouts
When you are locked out, you want a quick response and someone who knows what they are doing. Call us for emergency assistance and we will dispatch a technician to your area straight away.
We unlock your Seat using non destructive methods, so you regain access with no damage to the vehicle. It is a lockout service built around one thing: getting you moving again with peace of mind.
What about a damaged lock?
After an attempted theft, a lock may need a repair or a rekey rather than a new key. We will explain the options before any work starts.

Auto Locksmiths for Every Vehicle and Every Area

Whatever the vehicle, the service is the same: an Essex auto locksmith at your door, a clear quote and a key that works first time.
Our auto locksmiths are not just Seat specialists. We work on Ford, Vauxhall, Volkswagen, Renault, Peugeot, Nissan, Hyundai, Mitsubishi, Volvo, Porsche and Jaguar Land Rover vehicles, and older makes such as Saab and Daewoo.

Our auto locksmith services cover all areas and locations across Essex, including Billericay, Ongar, Basildon and Chelmsford, with the same service in London and Kent. Give us your postcode when you call and we will book an appointment at a time that suits you.
Advice Before You Book
If you have a problem with your key, our team will give you honest advice on the phone first. Some issues, such as a worn part or a flat battery, have simple fixes. Others need a new key. Either way, you get clear information and a quote before any work starts.
Reliable Results
Our testimonials and Google reviews tell the same story: reliable results, fair prices and a quick response. You can find us on Google Maps or through the Google app, and our number is on every page. When you need assistance on the road, we are a call away.
