As a very fortunate and proud owner of a new Mercedes with Keyless Go, I'd rather not make it easy for thieves to make off with car whilst I'm shopping with the wife, out for a meal or a meeting. This is what can happen (it's been shared on the forum before).

* guy parks his car, goes into a building
* SUV pulls up and two thieving team members, T1 and T2, get out. T3 stays in the SUV.
* T1 wearing a back pack follows the victim, on hand held comms, stays in contact with T1/T3..
* T2 goes to the car
* a few seconds later T3 uses the SUV as a visual blocker, physical barrier and getaway vehicle[1], between the victim and his car.
* T2 accesses car and drives off
* T3 pulls over, picks T1 who has run out
* Victim comes out of building, bewildered
All over in a few minutes. Either.... T1 and T2 have an RF bridge (two laptops or RPis, maybe mobiles) and antennas to capture, share and retransmit messages between the key and car. Or... They have a key and clone it via ODB or otherwise. I'm going to get a Disklock methinks.
Solutions (primarily when you or your family are not in a physical vulnerable position)
* Keyless Go can not be turned off on the car itself (confirmed by MB Grimsby)
* Keys can be turned off (stated by a forum member, but I can't find the thread) by a quick double press. Reactivated by a single press. I confirmed this today.
* Jamming pouch. It's effectively a flexible, flat Faraday Cage, stopping RF (around 433MHz) getting in or out. I tested this out today on my W222. It works perfectly denying RF drum a fully capable key. The pouch is flat enough to fit in a jeans pocket in comfort and cost around £2. Here's mine
[1] in case things go south. They are not mugging the victim, so prefer non-violent methods.
