Information about MULTLOCK
MULTLOCK cylinders, locks and access control
Origin and international presence of MULTLOCK
MULTLOCK, the common name for Mul-T-Lock®, is an Israeli brand founded in 1973. Its first development was a four-way lock, and a few years later it incorporated telescopic pin technology into its cylinders. Since 2000 it has been part of the ASSA ABLOY group, a worldwide specialist in opening, closing and access control solutions.
With more than 50 years in the trade, Mul-T-Lock develops products for homes, shops, industries, institutions and vehicles. The brand is present through distributors and authorised centres in numerous countries and holds a recognised position in the high-security cylinder segment, above all for key-copy control, master-keying options and its mechanical systems with multiple locking levels.
Product range for residential and professional security
The MULTLOCK catalogue goes beyond the conventional cylinder. Its platform-based structure makes it possible to adapt the same key technology to different cylinders, padlocks, locks and entry points. This is useful when a home, business or residents' association needs several doors to work with orderly permissions.
- Euro-profile cylinders, round-profile, rim, double, half cylinders and versions with a thumbturn.
- Mechanical locks, multi-point locks, deadbolts, padlocks and solutions for wooden doors, metal doors or commercial entry points.
- Keyed-alike systems, where one key opens several authorised entry points, and cylinders with a different combination for each door.
- Hierarchical master-keying for residents' associations, offices, education centres, warehouses or buildings with restricted areas.
- Defendo®, an external armoured protection that complements the cylinder against extraction, breakage and drilling.
- Electromechanical and access control options, such as CLIQ®, for installations that need to manage permissions in a more advanced way.
Security technologies and certifications
MULTLOCK's traditional technology is based on telescopic pins: each position combines internal and external elements that must align correctly to allow turning. On the security platforms, this system is complemented by special pins, steel inserts and additional locking lines to make bumping, picking and drilling more difficult.
The MTL™800 system integrates three layers of locking: telescopic pins, a locking bar with lateral pins and a moving Alpha Spring element on the key. The brand declares a high resistance to bumping, picking, drilling and other forms of manipulation. Its versions of the MTL™400, MTL™600 and MTL™800 platforms incorporate a steel bar to improve resistance to breakage of the cylinder.
The magnetic control card makes it possible to request duplicates at authorised centres with the key's encrypted code. Certifications, such as UNE-EN 1303, SKG or others, depend on the reference and the distribution market; the data sheet of the specific cylinder must confirm its grade. To maximise security, a locksmith should check that the cylinder does not protrude and that the escutcheon is compatible.
Platforms and models for each type of door
The Classic platform is an established mechanical solution for homes, storerooms, small businesses and doors that require a cylinder, padlock or lock with a single key organisation. It offers keyed-alike options, master-keying and, in certain configurations, 3 in 1 combination change. It is suitable when a reliable system is sought without reaching the complexity of a higher patented platform.
MTL™400 and MTL™600 are designed for users who want to reinforce key control and cylinder resistance on the front doors of flats, detached houses or premises. For entry points with a greater demand, MTL™800 suits single-family homes, shops with goods, offices and complex master-keying. It is backwards-compatible with the earlier MT5®+ platform, which can make it easier to upgrade existing installations without modifying the whole key structure.
Advantages and points to consider
A notable advantage of MULTLOCK is flexibility. The owner can use one key for several authorised entry points and keep other spaces restricted by means of a well-designed master-keying scheme. Copy control by means of a card also reduces the likelihood of unauthorised duplicates. For second homes, residents' associations or businesses with staff, this organisation brings order as well as mechanical protection.
Cost and planning are the main aspects to weigh. High-security cylinders, their escutcheons and controlled copies usually require a greater investment than a basic cylinder. In addition, it is not advisable to create master-keying without anticipating future additions or removals of users. On an internal door or a reduced-risk entry point, a simpler solution may be enough. If, on the other hand, the door is deteriorated or the frame does not close well, that structural problem must be resolved first.
Installation and maintenance of the MULTLOCK cylinder
Installation begins by measuring both halves of the cylinder from the point of the fixing screw. You must choose the right length, the compatible cam and the correct type of cylinder for the lock. The cylinder must be protected by the escutcheon, without protruding significantly to the outside. On doors with a thumbturn or emergency function, the behaviour from both sides is also checked.
For its care, it is worth using a dry lubricant specific to cylinders and avoiding dense oils, which capture dust. A key that jams, a rotor with play, an irregular turn or signs of an attempted forcing justify a check. After mislaying keys, changing tenant, finishing building work or suffering an attempted intrusion, changing the cylinder helps to regain control of the entry point.
