smart relay
A smart key is a vehicular passive entry system developed by Siemens in 1995 and introduced by Mercedes-Benz under the name "Keyless-Go" in 1998 on the W220 S-Class, after the design patent was filed by Daimler-Benz on May 17, 1997.
Numerous manufacturers subsequently developed similar passive systems that unlock a vehicle on approach — while the key remains pocketed by the user.
Afternoon all.
Is there anyone around in here who has reasonable knowledge of the 12V system on the MG5?
What I am looking to do is to possibly use a smart relay to charge a second 12V battery to run some "other equipment" when the vehicle may be shut down.
Thanks in advance
