Lock cylinder and key. Porsche 911 63-67  ›  90153165120

The OE Match Lock Cylinder And Key is a replacement mechanical door-lock barrel supplied with a matching key for early Porsche 911 models.

• Porsche 911 2.0 01/63-07/67

Installed within the exterior door-handle locking mechanism, the cylinder allows the door to be securely locked and unlocked using the key. Turning the key rotates the internal lock mechanism, which in turn operates the door latch locking components.

On classic vehicles, decades of use can cause the original lock cylinder, tumblers and key to wear. Dirt, corrosion, damaged wafers or a worn key can make the lock stiff, unreliable or difficult to operate.

Replacing a badly worn or damaged lock cylinder restores smooth mechanical operation and provides a fresh matching key for the replacement barrel.

What This Product Does:
The lock cylinder provides the keyed mechanical interface between the driver and the door locking mechanism.

It is designed to:

• Allow the door to be locked using a key.
• Allow the door to be unlocked mechanically.
• Operate the locking mechanism within the exterior door handle.
• Provide controlled access to the vehicle.
• Replace a worn or damaged original lock barrel.
• Replace a lock that has become seized or difficult to turn.
• Provide a new matching key with the replacement cylinder.
• Restore dependable operation during vehicle restoration.
• Help maintain the original-style mechanical locking arrangement.

• Key becoming difficult to insert.
• Key becoming difficult to remove.
• Lock requiring excessive force to turn.
• Cylinder feeling stiff or rough.
• Key only turning after repeated attempts.
• Lock intermittently refusing to unlock.
• Door failing to lock consistently.
• Key needing to be moved or wiggled before the cylinder turns.
• Cylinder rotating without operating the door lock correctly.
• Internal mechanism sticking.
• Visible corrosion around the key slot.
• Dirt or debris inside the lock.
• Key becoming heavily worn.
• Key bending or twisting during use.
• Broken or damaged key remaining inside the cylinder.
• Lock cylinder becoming loose inside the door handle.
• Physical damage following attempted forced entry.

A worn cylinder may continue working intermittently for some time, but as wear progresses it can eventually leave the owner unable to lock or unlock the door normally.

Replacing a faulty cylinder helps restore:

• Reliable door locking.
• Smooth key operation.
• Secure mechanical engagement.
• Easier vehicle access.
• Reduced risk of a key breaking inside the lock.
• Correct operation of the exterior door-handle mechanism.
• Improved security compared with a badly worn lock.
