McGrath Key Blank - Suits NX6 Lock

McGrath Key Blank - Suits NX6 Lock

This McGrath key blank is the uncut blank for the mechanical override key used on the McGrath NX6 digital smart lock. It supplies your locksmith with the correct key profile so a spare or replacement override key can be cut to your existing lock.

The mechanical override lets you open the lock with a key if the batteries ever go flat, giving you a reliable backup to the digital credentials. Keeping a cut spare on hand - stored away from the door - means you are never locked out while you source fresh batteries.

This product is an uncut key blank only. It does not include a lock, a cylinder, or a pre-cut key, and it must be cut by a qualified locksmith to match your original key.

Estimated Dispatch
Usually same day if ordered before 11am AEST (excludes weekends and public holidays).

Key Features

• Correct key profile for the NX6 mechanical override cylinder - your locksmith cuts it to match your existing key.
• Provides a spare or replacement backup key for battery-dead access.
• Supplied as an uncut blank - no lock, cylinder, or pre-cut key included.
• Genuine McGrath blank for a precise fit to the original cylinder.

What's in the Box

• 1 x McGrath uncut key blank (NX6 profile)

Suitable Uses

• Cutting a spare mechanical override key for a NX6 smart lock while the original is still available to copy.
• Replacing a lost or worn override key (a locksmith can often decode or impression from the cylinder).
• Keeping a backup key off-site or in a key safe for battery-dead lockouts.

Cut to your existing key
A blank carries the profile only, not your key cuts. Bring it to a locksmith with your original NX6 key so the new key is cut to the same combination. If the original is lost, a locksmith may be able to decode the cylinder. See our guide on the mechanical key override for how backup keys work.

Available Finish Options

• 
  Natural (Uncut Blank)
  (This Product)
  STK MLSPNX6KB

A key blank is supplied as raw metal; the finish shown is the natural blank prior to cutting. Finish selection does not affect functionality.

McGrath Key Blank Family

McGrath uses different key profiles across its lock range. Order the blank that matches your lock - the profiles are not interchangeable between models. Browse the full keys and key blanks for smart locks category to find the blank or cut key for your model.

Matching Override Cylinders

If the cylinder itself is worn or you want a fresh keyed set rather than only a spare key, McGrath supplies complete replacement override cylinders (each with 2 cut keys) for the NX6 lock. Order these when you also want to change the key combination.

Keyed Alike (KA) shares one key across multiple locks; Keyed to Differ (KTD) has its own unique key.

Frequently Asked Questions

Is this a working key I can use straight away?
No. It is an uncut blank. It carries the correct NX6 profile but has no cuts, so a locksmith must cut it to match your original key before it will operate the lock.

Will this fit any McGrath lock?
No. McGrath uses different profiles across its range, so this blank suits the NX6 lock only. Ordering the blank for the wrong model means it will not enter the cylinder.

I lost my only override key - can a locksmith still help?
Often yes. A locksmith can sometimes decode or impression the cylinder to determine the cuts, or you can fit a fresh replacement cylinder that comes with 2 new keys. See the override cylinders listed above.

Where should I keep the spare key?
Never inside the house behind the locked door. Store it off-site, with a trusted contact, or in a key safe. Our key storage guide covers safe options.

Where is the keyhole on my McGrath lock?
The override cylinder is usually concealed on the smart lock body. Our guide on where the keyhole is hidden shows the common locations.

Additional Information

The mechanical override is the last layer of a smart lock's access stack - it works even when the batteries are flat. Cutting a spare blank now, while your original key is available to copy, is the cheapest insurance against a battery-dead lockout later.
