- One complete flip-style remote housing with integrated blade
- Pre-installed 434 MHz circuit board and ID48 immobiliser chip

Optional: blade cutting from a photo
Tick the Cutting from picture option at the top of this page and upload a clear vertical photo of your original key blade. We cut the new blade to match, wipe your photo from our system once the job is finished, and ship the key cut-and-ready. This saves you a locksmith visit for the mechanical side of the job — the programming step is still required.
Vehicle compatibility
This key is a direct replacement for the factory-fitted remote on the following models and year ranges. If your original key matches the photos on this listing — five buttons in the same layout, flip blade, black-and-white shell — it is the correct part.
| Brand | Model | Chassis code | Year |
|---|---|---|---|
| Seat | Alhambra | 7N | 2010–2020 |
| VW | Sharan | 7N1 / 7N2 | 2009–2016 |
| VW | Multivan V (T5) | 7H / 7E | 2009–2015 |
*If you're unsure, you can always ask us or send us a clear photo of your current key — we'll confirm fit before you pay.
Programming: who can do it
A new remote key for these models has to be taught to the car's immobiliser before it will start the engine or operate the central locking. For the 5K0837202AD platform the picture looks like this:
- VW / Seat main dealer — in most cases no. Dealers are often unable to pre-code aftermarket blanks.
- Independent garage with key equipment — yes.
- Specialist auto-electrician — yes.
- Professional vehicle locksmith — yes, and usually fastest.
We recommend calling a local mobile locksmith before you order and asking whether they program aftermarket ID48 MQB-platform keys for VW/Seat — most will say yes and quote a flat fee.
Please note: this is an aftermarket replacement part, not an original OEM product. It is engineered for compatibility with the original factory key and carries a 12-month warranty. Trademarks and brand names are used solely to indicate vehicle compatibility.
When buying a car key, please pay attention to choose the correct model for you.
Please look for:
-the number of buttons and the symbols on them
-the location of the LED lamp, if present
-the shape of the blade
-if your key looks different, please ask us about compatibility
