Review: Secure garage door - The pair of Bulldog garage door security locks arrived as promised on time. Well pleased with the construction of the the locks as the design of them is very good and very sturdy. Due to the price of them I was a bit hesitant on buying them but after reading the reviews they made up my mind. Just a bit of effort to fit them by creating holes in the garage floor to install them. They were registered and this gives a five year warranty which is worth doing, also registered the keys in case they are mislaid or damaged which costs an extra five pounds per lock. Just happy that it secured the garage door for the future.

## Questions & Answers

**Q: Is this OK to use on the outside of the garage, is it waterproof?**
A: Yes, it is designed to be used on the outside of the garage door. It is supplied with a plastic dust cap which will help prevent water getting into the lock.

**Q: Does this come with a cover to keep water out of lock?**
A: I bought mine about 5 years sgo, it did come with a cover over the bolt, but make it water tight around the bolt, as the water will fill up the hole you've drilled, & make the bolt rusty.

**Q: Is the key cylinder drill proof, and the cylinder pin hacksaw proof**
A: yes it is drill proof and hawsaw proof and i find it a excellent garage door lock                    bill

**Q: My garage has a 2cm high piece of rubber along the end of it (for reducing noise and water getting through I think); could I still fit this?**
A: Would think you would have to fit it over the rubber as it needs to be flush on the ground think the bolts are higher than 2cm it is a good product .

### ⭐⭐⭐⭐ Great lock for the price!
*by S***I on 11 August 2016*

Well made and very robust. All the fittings necessary are supplied, together with simple, clear instructions. I've only given it four stars as I would have preferred a better quality traditional keyed lock, rather than the cylindrical one supplied, as the depth of the 'indentations' are not quite as varied as I would have liked for security. Generally the greater the variation in depth the harder it would be to pick. In the early days of cylindrical locks, when the diameter of the hole was much smaller, it was often possible to open such a lock with a biro! Having said that, it should not be taken that this lock would be so easy to pick, not a bit! The diameter of the hole is much bigger than the ones described above and the variation of the slots is much more varied and a bit deeper, so I'm sure it would easily defeat all but the most skilled thief with the right tools. The opportunist thief wouldn't have a chance defeating this lock by picking it and to get past it any other way would involve a lot of noise and probably portable power tools. I would thoroughly recommend this lock as a good compromise between cost, security and ease of use, in order to protect the contents of most garages. It takes a bit of effort to fit as you obviously need to concrete the locking tube's receptical into the ground, but it's not difficult and was all done in a couple of hours start to finish. Provided you appreciate that if someone REALLY wants to get in, they will, there is little out there to beat this lock for the price and believe me I looked hard! Oh, and it's made in Britain, what's not to like!
