Is it OK to lock the RAV4 EV from the outside with the key and leave the electronic part of the FOB inside? I'd like to do this to minimize risk of damaging the FOB when I go off to ride or race my bike or go swimming. I'd guess that this is OK from reading the manual, but I'd like to make sure that this won't run down its battery or enable people to open doors by pulling the handle since it is close by. TIA for any info.
