Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Miguel King –
This ECM arrived quickly and was exactly as described for my 2015 Mercedes-Benz GLK-Class. Installation was straightforward since it came already VIN programmed, which saved me a lot of time and hassle. After swapping it in, the vehicle started right up with no issues, and everything runs smoothly. I appreciate the clear communication and support during the purchase.

Easy swap and had my GLK running like new in no time—definitely worth it! The unit was perfectly programmed and arrived quicker than expected.
