Cylinder Lock Replacements or Upgrades

Common Reasons To Replace or Upgrade Your Cylinder Locks:

You don’t need to wait until a cylinder completely fails before considering replacement. There are several practical and security-related reasons why you might want to change or upgrade your existing door locks.

Common reasons include:

• Faulty or damaged locks – a worn cylinder may become stiff, unreliable or increasingly difficult to operate.
• Lost or stolen keys – replacing the cylinder prevents missing keys from continuing to operate the door.
• Moving into a new home – changing the locks provides reassurance that previous occupants, contractors or other keyholders can no longer access the property.
• Moving into new business premises – replacement cylinders allow you to control who has keys to your new premises.
• Improving door security – older or basic cylinders can be upgraded to higher-security options with features designed to resist common methods of attack.
• Meeting security or insurance requirements – some insurers may specify particular standards or levels of door security. Depending on the type of door and complete locking system, this may include locks meeting recognised standards such as BS 3621.
• Burglary or attempted break-in damage – a cylinder that has been attacked or damaged should be assessed and replaced where necessary.
• Keyed-alike locks – compatible cylinders can be configured so that several doors operate using the same key.
• Smart or keyless entry – suitable existing locks may be upgradeable to compatible smart-lock or keyless solutions.

If your key is becoming difficult to turn, the cylinder isn’t always responsible. Poor door alignment or a fault elsewhere within the door locking mechanism can create similar symptoms. Our engineers can identify the underlying problem before replacing components unnecessarily.

Where improved security is required, we can advise on suitable anti-snap and anti-pick cylinder locks and other higher-security options for your particular door.

We can also advise on recognised security standards applicable to the complete door and locking system, including BS 3621 where relevant. BS 3621 relates to thief-resistant lock assemblies operated by key from both the inside and outside of the door, and is a standard commonly associated with security requirements for external doors.

Correct cylinder sizing is also important. A replacement should be appropriately sized for the door and surrounding hardware rather than simply fitting any cylinder that operates the lock. Our engineers will assess the existing installation, fit the appropriate replacement and check that the door locks and unlocks correctly afterwards.

For properties with several compatible doors, keyed-alike cylinders can reduce the number of separate keys you need by allowing multiple locks to operate from a single key.

If the fault involves more than the cylinder itself, Window Doctor also provides door lock replacements, door locking mechanism repairs and other specialist door repairs.
