The master key lock system is created to allow for all the door cylinders required be they Euro cylinders of any size. (Every lock is built to be opened by the master key if required).

High Security Locks

Kite Marked TS007 cylinders are designed to be drill resistant even to diamond tipped drills. The cylinders sometimes referred to as barrels are tested to very demanding standards before achieving the kite mark status. The British Standards Institute have to ensure that they are attack resistant to drilling, bumping snapping and picking.

In addition to all this the cylinder barrel is endurance tested to be able to function after a minimum of 100,000 open and close cycles. It is tested under extremes of temperature both hot and cold.

The differ or servant keys will open there own doors and others if stipulated. Euro Security Cylinders are available in a variety of sizes to suit all door thickness’s including PVCu doors. All sizes also come as a cylinder with thumb turn. In addition single or half cylinders are available were only a visible key on the outside is required. The new standard for these security euro locks is current Kite Mark which protects the end user. Cylinder Barrel Locks are available without a master key where door cylinders are not required to be opened by more than one key.

Suited or keyed alike is an option whereby more than 1 cylinder lock can be opened by the same key but there is no overall master key. Other features apart from anti-bump, bump resistant, & anti-snap is anti-drill and anti-pick. TS007 approved euro cylinders are a high security door cylinders designed to meet current insurance requirements for domestic and commercial applications where security is paramount.

Bump Resistant Locks

Bump resistant (anti-bump) means that the lock will resist a process called bumping, this requires a dedicated bump key to suit the door cylinder profile, the key is specially designed by unscrupulous individuals to aid illegal access.

It is not widely used by reputable locksmiths. The key is moved in and out of the lock rapidly to try and line the pins up so the key can be turned. This is not a very common means of access as the process can be quite noisy.

Anti Snap Locks

Anti-snap euro cylinders have a sacrificial cut on the outer side of the body so that should someone try and snap the cylinder the mechanism within the cylinder locks preventing illegal access. Anti-Drill function ensures by means of hardened pins within the cylinder that a drill is unable to penetrate the key way again preventing illegal access. Anti-Pick ensures that locksmiths picks in the wrong hands are not able to manipulate the operating pins.

MKS would always recommend you check with your insurer regarding the use of an approved security lock as they are as keen as you are to keep burglars out of your property(s).

Cylinder price can vary by level of security required so external doors or first entry point need to be the best protected the use of a 3 star high security cylinder here is strongly recommended.

Of course it is not always necessary to use such high security locking hardware and other door furniture, for instance to protect a garage or shed full of garden equipment. Here it is good enough to make the potential thief aware that locks are being used and to take action to make it harder for them to force the door / lock, good padlocks being one way to secure such buildings. This may well stop all but the most determined burglar.

To ensure reliable service from your security product we would recommend that you service the item at a frequency detailed in our maintenance leaflet. Always keep a spare key somewhere safe as a locksmith call out on a cylinder that is hard to break into can be expensive.
