A high-quality analog of the original flip-out ignition key case in a modern style for Seat cars is the perfect solution for replacing a worn or damaged key, allowing you to keep the working electronic components. Product code: AST4. The new case design ensures comfortable use, a reliable key flip-out mechanism, and a stylish appearance.
The product is an empty case without electronic parts. Seat car owners need to transfer the chip, transponder, and board from their old key into the new case. The product photos clearly show an example: on the left – the old key; on the right – the new replacement case. The kit includes a branded Seat logo emblem for installation on the case, maintaining the authentic look.

This case fits many Seat car models and is a full-fledged alternative to purchasing an expensive new key from an official dealer. It is an economical and practical solution for restoring the functionality and appearance of your key.
Advantages of the Seat AST4 Key Case:
- Modern design: Ergonomic shape and high-quality materials.
- Durable mechanism: Reliable spring and latch for long-lasting flip-out operation.
- Easy installation: Possibility to independently transfer electronic components from the old key.
- Full compatibility: The case is specifically designed for Seat key electronic units.
- Cost savings: Several times cheaper than buying a new programmable key.
What's included in the kit:
- New flip-out key case.
- Branded emblem with the Seat logo.
- Mounting elements (if needed).
Important: This product is a case (shell) and does not contain electronic components for starting the engine (chip, board). To function, you must use the "internals" from your old key. If the old key is lost, a new chipped key will need to be made and programmed.
