If you put the fob in the hitch safe, do you still have to take the battery out of the fob to avoid having the doors unlock due to fob proximity if someone tried to open the back gate? Parking lot thieves will spy on lots and watch for drivers to hide their keys.
Just a psa: the hitch safe can be overcome using at least two shim methods. Here is a link to the fastest:
I also wonder if it would be prone to a small prybar attack as well Until they put a gate guard on it, the hitchlock key safe is not safe at all for any thief with basic tools and Youtube. Too bad the hitch cover won't fit on top, that would add a good layer of keeping the hitch lock hidden from view.
A gun vault that locks to and hides under your seat may be a better option. Sits down low, and thieves won't get a good view of you hiding it vs conspicuously putting it in your hitch.
I try to take an old rig with me when I whitewater kayak and put the key in a waterproof pouch around my neck. If I lose my boat I still have my key. I've take my 200 series fob that way too, but worry condensation may damage it, so lately I hide the key in a really smart place (pm if interested) and the battery in a second also good hiding place. Metal key stays with me. Thankfully no break-ins yet to test my hiding spots, but I really doubt any thief would find where I hide the key and battery.
Too bad we have to mess around with this stuff. Parking car thieves are real dicks. I always worry when I leave my car for a long hike/boating/biking journey. Best advice is leave nothing of value in the car, and park in busy lots. I have seen countless break ins when I have been out, and the majority I have seen are in the lesser used lots, and lots where users tend to be gone a long time.
