Sounds like the eis has a problem
There is a company that repairs the electronic ignition switch

MandBspecialist.com

As a temporary solution you can buy a battery brain t3 from Amazon

It is a remote battery disconnect so you can shut off power to the car using the remote instead of having to pull a relay

Perhaps you can send an email to the people at Mandbspecialist and get some input from them. If they know how the ignitions work they should be able to tell you.
