Ignition key housing for SEAT cars – this is a new, quality outer shell (without electronic components), designed to replace the worn or damaged housing of your key. The product is perfectly suited for SEAT models: Altea, Alhambra, Arosa, Exeo, Ibiza, Leon, Mii. The delivery set includes the brand emblem of SEAT, which can be installed on the housing, allowing you to preserve or restore the factory appearance of the key.
This ignition key housing is a simple and cost-effective solution for those whose electronic part (chip, board, battery) is functional, but the plastic housing itself, the buttons, or the logo are damaged or worn out.
Our store offers two variants of the housing, which differ in the number of buttons and, accordingly, functionality:
- Product code AST3.A – key housing with two buttons. A standard option for basic functions.
- Product code AST3.B – key housing with three buttons. Suitable for keys with an additional function (e.g., trunk opening).
Both variants feature high manufacturing quality: the plastic is scratch-resistant, the buttons have a clear, tactile feel, and the assembly ensures a reliable connection of the housing halves. Installing your electronic 'guts' and the metal blade part into the new housing is generally a straightforward process that can be done independently.

The image above shows an example of a similar key housing, allowing you to visually assess its design, button layout, and quality of workmanship.
Advantages of purchasing this housing:
- Cost savings compared to purchasing a new key from a dealership.
- Preservation of the original electronics and the car's immobilizer. No expensive reprogramming is required.
- Quick restoration of the key's appearance. No more scuffs, chips, or cracks.
- Easy selection – you only need to determine the required number of buttons on your old key.
Before purchasing, make sure you have removed the housing from your old key and visually identified its type (2 or 3 buttons), as well as the matching shape and internal slots for the board. This housing is not an electronic device and is sold solely as a mechanical shell. All electronic components, the battery, and the metal blade are used from your old key.
Refresh the appearance of your SEAT key easily and inexpensively! Choose the suitable housing variant (AST3.A or AST3.B) and place your order.
