Sliding screen door Locks & Security Screen door Locks

Screen door locks generally last between 10 to 15 years with normal use.
You can spot by looking at the handles when it’s time to replace the lock, “handles are saggy not at 90 degrees”.

Types of locks

There are a few different types of screen door locks that door manufacturers have used.

  • Main types of locks are; single way locking & three-way locking.
  • Hinged screen doors & Sliding screen doors in either 1 way locking or 3 way locking.

The most reliable brand is Whitco in security screen door locks followed by Lockwood.

Security Screen door locks don’t last forever despite the brand of lock.

Another upside to the Whitco product is, they are not overpriced & readily available.

Lock Cylinders

Lock cylinder get over looked all the time.
Disk Lock cylinder (Cheap ones) are installed when you buy a security screen door or sliding security screen door. “Which defeats the point.”
Disk lock cylinders should be banned, they provide very little security. (Attend Locksmiths don’t sell or install them)
Here is the Good type of Lock cylinder AKA “Lock Barrel” that actually provides security & can be keyed to match your other locks. (one key for all locks)

3 way locking screen doors

The 3 way locking doors provide much better security from a physical forced entry point of view, but with our Queensland weather these bolts move out of alignment & need to be adjusted.


Once the bolts & strike plates are adjusted the movement in the property will not affect the 3-way locking bolts as much.

Each house moves a different amount & allowing the adjustment extra room will reduce the alignment problems and your door will operate for many years to come much more reliably.

This is not a difficult job to do & most Locksmiths get calls all the time for this problem.

Generally speaking, the job is a quick fix & the cost is just a service call.
