Which cylinder lock do you need?

A cylinder lock is the separate cylinder into which you insert the key. For exterior doors, the cylinder in particular determines how much resistance your door offers against burglary methods such as core pulling, drilling, lockpicking, and the bumping method.

Standard cylinder lock

For doors that you want to operate with a key from both sides. This is the most popular version for front and back doors.

Knob cylinder

Handy when you want to quickly open the door from the inside without a key. Especially popular for front doors, back doors, and escape routes.

Identical cylinders

Ideal if you want to open multiple doors with the same key, for example the front door, back door, gate, and shed.

Why SKG 3 is important for a cylinder lock

For exterior doors, SKG 3 is the safest choice within the SKG quality mark. An SKG 3 cylinder lock has been tested against severe burglary methods and offers more resistance than a standard cylinder without a quality mark.

  • Core pull protection: protects against the extraction of the cylinder core.
  • Hardened steel bridge: makes the cylinder stronger against breaking and forcing.
  • Protection against drilling and lockpicking: important in modern burglary methods.
  • Certificate: prevents keys from being duplicated without permission.

Buying a cylinder lock: how to choose safely

1. Choose the right security

For exterior doors, we recommend SKG 3. For interior doors or less high-risk applications, a lighter solution may sometimes suffice.

2. Measure the cylinder size

Measure from the center of the mounting screw to both sides. If in doubt, use our measuring manual.

3. Determine the operation

Choose standard key operation, a knob on the inside, or multiple cylinders that work with the same key.

Popular M&C cylinder locks

M&C has multiple series. The difference lies mainly in key security, certificate verification, finish, and price level.

M&C Minos
Good basic choice for secure exterior doors.
M&C Matrix
Strong choice with extra key control.
M&C Condor
Popular SKG 3-cylinder with strong security.
M&C Move

Measure and replace cylinder lock

The correct size is important. A cylinder lock that protrudes too far is more vulnerable to burglary, while a cylinder that is too short will not fit properly. Therefore, first read how to measures cylinder lock or view our explanation about replace cylinder lock.

Frequently asked questions about cylinder locks

These answers will help you choose the right SKG 3 cylinder lock faster for your front door, back door, shed door, or multiple doors with the same key.

How much does a good cylinder lock cost?

A good SKG 3-cylinder from M&C At MC-Cilinder, they cost from €52,50 per piece. The exact price depends on the series, the cylinder size, and whether you choose a rotary knob. If you order multiple keyed-alike cylinders at the same time, you pay less per cylinder.

What is the safest cylinder lock?

For exterior doors, an SKG 3 cylinder lock with core pulling protection is the safest choice. These cylinders offer greater resistance to core pulling, drilling, breaking, and manipulation. Preferably combine the lock with matching security hardware for maximum protection.

What is better: SKG 2 or SKG 3?

SKG 3 offers greater resistance to burglary than SKG 2. Therefore, we recommend SKG 3 for front doors, back doors, and other exterior doors. SKG 2 may sometimes be sufficient for less high-risk applications, but it is not the strongest choice.

Can I order multiple cylinders with the same key?

Yes, that is called keyed alike. You can then open the front door, back door, gate, and shed, for example, with the same key. This is convenient for homes, commercial properties, and situations where you want to use fewer separate keys.

How do I know what size cylinder lock I need?

Measure from the center of the screw hole to the inside and outside of the door. This will determine the correct cylinder size. A cylinder must not protrude too far, as this increases the risk of forced entry.

Do I also need to use security hardware?

Security hardware is highly recommended for exterior doors. A good cylinder lock and matching hardware reinforce each other against core pulling and forced entry. This combination is particularly important for front and back doors.

Which M&C Which cylinder lock suits my door best?

For a strong foundation is M&C Minos compatible. If you require additional key verification, choose M&C Matrix of Move. M&C Condor is popular due to its strong price-quality ratio. For advice, use the cylinder wizard.

Which cylinder lock per door type?

Not every door requires the same cylinder lock. The right choice depends on the risk of burglary and the use of the door:

  • Front door: Always an SKG★★★ cylinder lock with core pull protection — this is the most attacked door.
  • Back door: at least as important as the front door; burglars specifically choose the least visible side. SKG★★★ here as well.
  • Shed, garage or storage room: an SKG★★★ cylinder, preferably keyed alike with the house.
  • Interior door: here a lighter cylinder or a knob cylinder for ease of use.
