Slam-to-Lock vs Lift-to-Lock Mortise

Slam-to-lock and lift-to-lock mortises both work with Simpled Slim model handles. The difference is how you lock the door.

Each mortise type requires a specific action. The differences and correct usage are explained clearly below.

The Two Locking Types (Simple Explanation)

1) Slam-to-Lock Mortise

What you do:

Close the door

That’s it — the door locks automatically

What happens:

The latch engages as soon as the door shuts

No handle movement is required

Think of it like:

A hotel door that locks the moment it closes

2) Lift-to-Lock Mortise

What you do:

1. Close the door
2. Lift the handle up
3. (Optional) Lock fully using key/app if needed

What happens:

• Lifting the handle engages the locking mechanism
• If you do NOT lift the handle, the door may not fully lock

Think of it like:
A door that needs an extra step to secure properly.

Test 1: Close the door

• If it locks immediately → Slam-to-lock
• If it does NOT lock or engage the full mechanism → continue

Test 2: Lift the handle

• If lifting the handle locks the door → Lift-to-lock
• If nothing happens → check installation or contact support

Slam-to-Lock is best for:

• Convenience
• High-traffic doors
• Situations where automatic locking is required

Lift-to-Lock is best for:

• Added security
• Doors where controlled locking is preferred
• Preventing accidental lockouts

• Slam-to-lock = Close door → locked
• Lift-to-lock = Close door → lift handle → locked

If your door is not locking, try lifting the handle first.

If you have followed the correct method and the door still does not lock:

• Check that the door is fully aligned and closed
• Confirm the lock is installed correctly
• Contact support with photos or a short video for faster help
