About This Part
In-vehicle detection antenna (OE 12697601-00, ref S6-3642400-D1) for the BYD smart key system. This compact cabin PKE antenna reads whether the fob is inside the car so keyless start and anti-lock-in work correctly, packaged as a slim black module with an integrated connector. It fits a broad recent range including the 2026 Sealion 06 EV, Song Pro DM-i, Song L DM-i and many more BYD variants. Replace the smart key antenna if the car no longer recognises the key from the cabin.

Frequently Asked Questions: OE 12697601-00
How do I check this module suits my car?
This antenna suits a wide spread of BYD models and variants, so the Sealion 06 EV in the title is one application among many. Find your own model year and variant in the fitment table on this page before you order, and do not go on the model name alone. If your build is not shown there, or you are unsure which variant you have, check the OE number on the old part, or send a photograph of the old part and its label through the quote route and we will confirm it against the OE number.
My old module has a different number on the label. What should I do?
This module is also known as S6-3642400-D1. Where the label on your old antenna reads that instead of 12697601-00, both references point at the same item and you are on the right listing. Copy the characters down exactly, including anything after the dash, because a suffix on an electronic part can mark a different variant. If what you have matches neither reference on this page, send a photograph of the label through the quote route and we will identify it before you order.
How long does this take to arrive?
Delivery takes 8 to 25 days from your order to your door. If your car is off the road waiting for it, say so through the quote route before ordering, and we will tell you what the line is doing so you know where things stand. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12697601-00.
What is the module made of?
This antenna is plastic. That is the material family and no more. No detail on the electronics inside or the connector type is given, so none is stated here and none should be inferred from the category name. The material means the module is light to handle, so support the body rather than the connector when it arrives. If the workshop needs a fuller specification before it goes in, send 12697601-00 through the quote route.
Where in the car is this fitted?
This module fits in the interior of the car. No side or front to rear position is stated, which is why this page does not name one, and no access route or fitting sequence is given either. It falls under control units and modules, so treat it as an electronic part rather than as trim. Confirm your variant in the fitment table before ordering, and if the module in your own car does not look like the photographs here, use the quote route before you commit.
Why is only one version of this module listed?
Only the Original/Genuine module from BYD is listed for this reference. The Aftermarket tier is empty against 12697601-00, so the page shows one price rather than a choice of two. That is a statement about what we can source, not about the module itself. If you would rather have an independent equivalent, ask through the quote route and we will tell you whether one exists for this OE number. Otherwise the version shown on this page is the one available to order.
