Do you know where the battery is installed to write that ...Wouldn't it be easier to just disconnect one of the battery terminals? If it has to be done frequently, keep the proper size wrench in the glove compartment.
I installed a remote controlled switch (latching 12v relay - intelletec from Amazon) in my 2013 Cityflame. The ON/OFF is on the front grill. I thought about doing a key, but decided I had enough darn keys. The push button is marine waterproof switch and it works well.2013 smart cabriolet can be towed four-down, but requires that the battery be disconnected. Anyone suggest (1) type and make of a switch, and (2) where is the best place to locate the switch?

some of my posts on the subject:I installed a battery switch in line on the negative cable that you unscrew the knob and it cuts the battery but you have to pick up the carpet and lift the floor. I went through 19 pages the other night on towing on this site and if I can find it again I'll continue. I'd say 80% of the respondents do not use the switch at all, without any problems. I experimented today, pull up parking brake step on the break put trans in neutral and turn of ignition to the 1 position far left and release the brake and the dash light goes out and a few minutes later neutral light goes out and the nothing has to be relearned, so what's the advantage of disconnecting the battery, unless some dimwits didn't follow the process and Smart felt they had to add that in 2009 so the won't have to cover warranty problems. Going to the Keys tomorrow and will keep battery connected and ignition off. I'll just use the bungee cord
The odometer on my '13 Pure (US version) does not accumulate miles while towing either with or without the battery disconnected. I have read on other posts that some do. Must be a difference in the car versions. I have towed thousands of miles in both modes, so I can't say if disconnecting is necessary. Probably safer to do it. I didn't because I only had one key and it was a hassle to wait for the computer every time I stopped so I could lock and leave. Now that I have a second key, I will use my switch again. Belt and suspenders maybe. YMMV (or kilometers)I'm not certain if the millage won't accumulate if you don't use a disconnect switch !
