So tuck the box behind a wheel or in a tight spot under the hood (provided you can pop the hood from outside, that is!).Does your Master Locklock have a serial number? If it doesn't, we won't be able to help you find your combination because we don't have a record of it. And the more confined the space you put the lockbox in, the harder you’ll make it for a thief to put a pry bar or pair of bolt cutters into action. Don’t shackle it to the car door handle, as at least one manufacturer suggests, because it’ll become an obvious target in an empty parking lot. Conceal the lockbox in the undercarriage or engine compartment, locking the shackle around something anchored and robust: a shock strut or engine-block mount, for example. And when using one on your car or truck, take a couple of extra steps to boost security.

It would be too easy for someone to walk up as though they were an innocent visitor, pop the shackle, and disappear with your key. So, again, don’t use a shackle model on your house or rental property. As stated above, all shackle models have a significant built-in weakness: the shackle can be cut, allowing the thief to retreat somewhere private to break open the box and steal the key.
