Seat fits an electronic transponder immobiliser across its range, so a Seat key is cut and then coded to the car before the engine starts. Some Seat cars use a folding remote key in the ignition, and others carry KESSY, the keyless locking and starting system of Seat. The registration tells Matt which of the two a car has.
Matt is with you within the hour in Leicester, and the same day across Leicestershire. Calls to 0116 442 2084 are answered day and night, and the quote is settled before any key work starts.
Each line below is a Seat key job that Matt attends in Leicester, and the method of each sits on its own service page.
Support for a given Seat and year is confirmed on the call, from the registration.
Four Seat terms describe how a Seat locks, unlocks and starts, and each one changes what a new Seat key involves.
| Seat term | Where the owner sees it | What Seat states about it | What it means for key work |
|---|---|---|---|
| Electronic engine immobiliser | Printed on Seat specification lists, and shown by the immobiliser lamp in the instrument panel. | The engine starts only with an ignition key that holds an individually coded transponder chip. Seat states that its models are equipped with one. | A cut blade alone does not start a Seat. The transponder in the new key is coded to the car. |
| Central locking with radio remote control | Printed on Seat specification lists. The key has lock, unlock and boot buttons and a key blade that unfolds. | A radio signal locks and unlocks the doors and the boot lid. Where the central locking fails, the key blade still turns the lock in the driver door. | The blade is cut, then the remote and the transponder are coded. Tell Matt whether the buttons, the blade or both have failed. |
| KESSY, Keyless Entry and Go | Printed on Seat specification lists on selected trims. Seat owner manuals call it Keyless Access, and the car has a starter button. | The key stays on the driver. Sensors in the door handles recognise it, and the engine starts from the starter button with the key inside the car. | A KESSY key is coded to the car as a keyless key. Tell Matt that the Seat starts from a button, and support is confirmed on the call. |
| Remote lock and unlock, SEAT CONNECT | Listed among the SEAT CONNECT connected services on equipped Seat cars. | The car is locked and unlocked from a mobile device through the connected service. | It is managed through the connected service setup Seat supports, not cut or programmed as a physical key. Inta-Lock works on the physical key, the locks and the immobiliser. |
An owner without the specification list to hand gives the registration, and Matt identifies the Seat key system from it.
A Seat key cut and coded beside the car, anywhere in Leicester.
Call Matt on 0116 442 2084The Volkswagen Group lists Seat in its Core brand group, next to Volkswagen and Skoda. For supported Seat work that requires Volkswagen Group manufacturer access, Matt carries ODIS.
Inta-Lock holds SERMI accreditation, and the SERMI scheme authorises access to security related manufacturer information where supported work requires it.
Seat defines its immobiliser by the coded transponder chip in the key, which is why coding is the step that decides whether a new Seat key starts the engine. That step is described under car key programming.
Five steps cover a Seat key job, and the first of them is a phone call that Matt answers himself.
A quote is agreed before work begins.
The key system on a Seat differs between ranges, trims and model years. The current Seat range in the United Kingdom is the Ibiza, the Leon, the Leon Estate, the Arona and the Ateca, and KESSY is fitted on selected trims within it.
Earlier Seat cars such as the Mii, the Toledo, the Alhambra and the Tarraco remain on the road in Leicester, and across their owner manuals Seat describes the folding remote key and, on equipped models, Keyless Access. The Volkswagen Group lists Seat and Cupra together as one brand entry, and Cupra key work is confirmed on the call in the same way.
The registration identifies the exact Seat, so Matt confirms support before he attends.

The person who answers a Seat key call is the person who arrives, because Matt East handles and attends the work himself. He trained as a locksmith from 2011 and moved into automotive work and equipment in 2019.
Garages and dealers have referred key work to him from 2021, and the job count stands above 1,000. For a Seat owner the accreditation that counts is SERMI, which sits beside the ODIS access carried for supported Volkswagen Group work.

Seat key jobs are attended on driveways, in work car parks and at the roadside throughout Leicester and the county. Matt is with you within the hour in Leicester, and the same day across Leicestershire.
Three Seat key situations hand over to a service page, and the makes closest to Seat have pages of their own.
A Seat with no working key is still given a new key on supported models, cut and coded where the car is parked. The recovery itself is set out under lost car keys.
Where the vehicle supports it, missing electronic keys are removed from the immobiliser memory. A mechanical blade still turns a physical lock unless that lock is changed or rekeyed.
Seat states that a car with keyless entry does not lock with the keyless fob inside it. A Seat key that ends up shut in the cabin or the boot regardless is reached by non destructive entry, the work described under locked out of a car.
Seat owner manuals also describe a lock cylinder on the driver door for the unfolded key blade, which serves an owner whose remote has failed while the key is in hand.
Seat key fob faults are handled under the car key fob repair service. Whether the remote is repaired or takes another route is confirmed after the fault is identified.
Seat sits in the Core brand group of the Volkswagen Group with Skoda and Volkswagen, and Audi belongs to the same group, so each of those makes has a key page here.
Comparison. A Seat main dealer and Inta-Lock each supply a key that is coded to one specific Seat.
Differences. The dealer route runs through the dealership, while Matt brings the key work to the parked Seat.
Similarities. Each route asks for details of the car and of the person requesting the key, because a Seat key is security related work.
Effects. Completing supported key work where the Seat stands removes the reason to move the vehicle solely for that job.
KESSY is the automatic locking and starting system of Seat, printed on specification lists as Keyless Entry and Go.
The key stays on the driver, the door handles recognise it and the engine starts from the starter button. Seat owner manuals call the same function Keyless Access.
No, a Seat does not start with a blade alone, because Seat states that the engine starts only with a key that holds an individually coded transponder chip.
The blade turns the door lock. The transponder is coded to the car before the immobiliser releases the engine.
Supported Seat key work is carried out where the car stands in Leicester, at home, at work or at the roadside.
Matt confirms on the call whether the Seat and its year is supported before he attends.
No, SEAT CONNECT remote lock and unlock is a connected service and does not take the place of a physical Seat key.
It is managed through the connected service setup Seat supports. Inta-Lock works on the physical key, the locks and the immobiliser.
A Seat driver door opens with the unfolded key blade when the remote fails, because Seat owner manuals describe a lock cylinder on the driver door for that purpose.
On selected models the cylinder sits under a cover on the door handle. A remote that stays dead after that is assessed at the car.
Seat notes that some owners store the keyless fob in a faraday pouch or box at home, which blocks the signal.
Seat also states that some cars let the owner switch the keyless function off. Whether a given Seat allows that is in its owner manual.
No, there is no set price for a Seat key in Leicester, because the figure is quoted for the individual car.
The key system, the model year and whether a working key remains each change the job. A quote is agreed before work begins.
Have the Seat registration ready and call Matt for a quote on the key.
