Welcome to Zentry Forced-Entry Security Solutions

Restoring Your Peace of Mind

After six years of research and development (to see Our Story click here), we are thrilled to introduce our Burglarybuster Locks - the world’s first ever and widely acclaimed locking devices for effectively securing every type of double French Door and Conservatory Door. 


For full product information and also details on How to Secure Single & Double Handled French Doors see SECURING FRENCH DOORS page here


The Burglarybuster Lock 1 is the solution for all opening-outwards French doors including single-handled French doors and the Burglarybuster Lock 3 works on all opening-inwards French doors.

Note the Following:

  • An average of one thousand (1000) recorded burglaries per day took place in the UK during 2016. However, it is estimated that at least six hundred extra (600) went unrecorded.

  • Approx. one in every three of these crimes occurred at a time when one or more of the home’s usual residents was in the house.

  • This means that, on average, approximately five hundred and thirty (530) such incidents occurred daily during 2016, with the real danger of injury or worse to a resident of the home.

  • Approx. two in every three of these crimes occurred where unlawful entry was gained through a door.

  • Most burglars want to know how they are going to get out before they enter, and so prefer to enter through a door.

  • The most vulnerable of these doors is the French Door.

  • Even if a French Door has a multi-point locking system, this door type needs a second (and discreetly positioned) independent strong lock to be secure.

  • The evidence therefore shows that French Doors need a second and last line of defence to protect against burglary.

  • Staying safe and secure while at home has now become the single most important home security need for residents.

“We have two pairs of one-handled French doors in our home and fortunately a friend of mine recommended your security system to me. Although it is now over twelve months since we installed the device I felt I should let you know that we had an attempted break-in last week and this was prevented by your Burglarybuster. Many thanks”

“As our garden backs on to a golf course anxiety surrounding the security at the back of my home increased dramatically last week when my next door neighbour suffered a break-in through his French doors. I now have your device fitted to my French Doors and when I am at home I feel a lot more at ease and also feel a lot safer.”

“We have three of your Burglarybusters in our larger than normal sized home (we have six children). Last week and for the second time in two years these locks prevented a break-in to our home. At three am last Thursday morning we awoke to hear the noise at one of the doors and disturbed three guys attempting to force the door open. When they had fled we discovered they had already got the main door lock open and would have got in but for your device. Many, many thanks and we will continue to recommend this excellent product to our friends and relations.”

“Having spent several months in Ireland and overseas looking for a means of securing my French door containing one handle I eventually stumbled across your Burglarybuster 1. It was fairly simple to install and works brilliantly and we are really happy with the degree of security it provides. My wife is also very pleased and comments regularly on how neat and effective it is."
