I'm going to have to store the XFR soon for a couple of months outside. I plan to pull the battery as the temperatures can push -30C sometimes in the overnights. I'll be testing and lubricating the trunk locks before I pull the battery to make sure I can get back in without using a saw in the spring.

The question is - what will happen to the electronics when the battery is put back in after 3+ months out of the car? Will I have to relearn the keyless remotes to the car is the big one.

What have you folks found with a longer term storage scenario?

Thanks!

 

You will need to relearn the window regulators “limit” switches, reset the emergency parking brake, and radio reprogramming. All easily done inside the car after the battery is replaced.

The rest is non-volatile memory.

Long term storage in the USA is done by renting a storage unit for about $75 a month.

 

I'm sure you know this but the trunk won't open on the switch without the battery in the car. So make sure your emergency key blade works. Or even safer, don't fully close the trunk...
