Grubrunner mentioned this mod in a string on the 2013 section of the forum. I told him I would be buying one and he asked me to review it once I did. He already has one and swears by it and I gotta tell ya, it's pretty awesome.
A lot of the road trips I take are out of cell range so the probability of me being able to use the uconnect app to unlock my truck if I lock myself out is slim.
This is extra piece of mind for less than $50 on Amazon. I will also be keeping a key to my girlfriend's Challenger in there in case she locks herself out in a similar situation and I'm out on the road able to assist.
Dial doesn't feel cheap, it's a good sturdy dial and you can tell when you spin it that it is of good quality.
The inside of the safe is pretty small but more than enough room for a fob and key or several keys.
Total install time is less than 60 seconds. Once the cams are locked in there with the locking mechanism there is no getting this thing off or out without the combination.
The combination is easy to change whenever you want. Grubrunner stated that he has never had an incidence of water or dirt getting inside the safe.
