I've found this clunky and hard to use compared to a previous lock box I've had. The bolt often gets jammed which is frustrating. The combination lock sometimes sticks as well so no dials move. Also the key fob blocker doesn't even work, had it all locked secure in the fob bag inside the box locked to the tow bar and boot still detected key and opened. Waste of money. In fact mine is barely fit for purpose, should really ask for refund/replacement. Expected better for price
