Lock Cylinders in Dubai - Replacement and Upgrade for All Door Types

The lock cylinder is the heart of any door lock - it's the component the key enters and turns to operate the locking mechanism. Most door locks in Dubai use a replaceable cylinder, meaning you can upgrade your security without changing the entire lock body. Replacing the cylinder is faster, cheaper, and leaves the existing door hardware in place.

Mr. Locksmith supplies and installs replacement lock cylinders for apartments, villas, offices, and commercial properties across Dubai. We carry a wide range of cylinder types, sizes, and security grades suitable for all standard Dubai door profiles.

Types of Lock Cylinders We Supply in Dubai

Euro Profile Cylinder

‍The most common cylinder type in Dubai apartments and offices. A narrow oval shape that fits into euro profile lock bodies - standard on most modern UAE apartment doors. Available in standard security and high security grades. Easily replaceable without changing the lock body.

Oval Cylinder

Common in older Dubai residential buildings and some commercial doors. Slightly wider than a Euro profile. Mr. Locksmith carries oval cylinders in standard, restricted, and high security grades.

Mortise Cylinder

‍Fitted into mortise lock bodies on the Dubai villa main entrances and commercial doors. The cylinder sits within the lock case and is secured by a setscrew. Replaceable independently - upgrading to a high-security mortise cylinder significantly improves villa security without replacing the entire lock.

Rim Cylinder

Used on surface-mounted rim locks and night latches -common in older Dubai buildings and secondary entrance doors. The cylinder sits in the lock body and connects to the rim lock mechanism with a connecting bar.

Patented Cylinders

KESO, Mul-T-Lock, and Abloy cylinders with restricted key profiles that cannot be duplicated without an authorization card. Available in euro profile, oval, and mortise configurations. The highest security cylinder option for Dubai properties.

Cylinder Sizes - What to Know Before Ordering

Lock cylinders are measured by their total length — the sum of the external and internal sections. Common sizes for Dubai doors:

• 30/30mm- standard apartment euro cylinder
• 35/35mm- standard apartment euro cylinder
• 30/40mm - door with a slight offset between inside and outside
• 35/45mm - thicker door or additional security fitting
• 40/50mm - heavy commercial doors

Mr. Locksmith measures your existing cylinder on arrival and supplies the correct size - you don't need to know the measurement in advance.
