Even with modern security systems, the traditional lock and key is still the foundation of good home security, providing access to owners and residents and restricting access to unwanted intruders.

If you need to replace a lost, stolen or broken house key or car key, or if you need a spare or duplicate, you need the services of local key cutters. These may be specialised locksmiths or any other businesses that offer a key cutting service.

Read this overview to find out what key cutters do, how much they cost and how to find the best local service in your area.

What do key cutters do?

Locksmiths and other key cutters can create and duplicate keys at their workshop or at your home, workplace or other location if they operate a mobile service. This involves cutting a blank key from your lock's manufacturer to match the exact shape and size of the old key.

Key cutters may only be able to create a new key if you have the original or a copy with you, but some locksmiths can cut keys based on codes or from taking an impression of the lock. Even a broken key may be copied if the pieces are still mostly intact.

If you have a key cutting emergency after hours, most locksmiths offer a 24/7 service. An emergency locksmith can retrieve a broken house key or car key from a lock and cut a new key on the spot.

What type of keys can be cut?

Most key cutters can duplicate a wide range of keys, but this depends on the service and the complexity of the key. This includes:

• House keys
• Car keys, caravan keys and other vehicles
• Office and commercial key cutting
• Garage and shed keys
• Keys for cabinets, windows, furniture and other items
• Padlock keys and other locking mechanisms

There are some limitations on what type of keys can be copied. Key cutters may not be able to duplicate more advanced keys, such as car keys with transponders. If you need to copy a master key, this will generally involve a more formal process, such as getting proper authorisation from the key provider.

What's involved in a key cutting service?

Keys are typically cut by an automated electronic key cutting machine. Some locksmiths may also cut keys using a manual punch system, but this is less common today and involves a higher level of expertise.

Key cutting machines are designed for specific types of keys, so a key cutting business will generally have a number of machines for specialised tasks. Together, these can copy most types of keys used in Australia.

The quality of your new house key or car key will depend on the skill of the key cutter and the quality of the machine and the key blanks used. High-quality keys are more likely to work first time, last longer and be less prone to breaking and going out of shape.

It's recommended that keys are copied from an original when possible. Keys that are cut from a duplicate set may not fit correctly in the key barrel, and this problem will be more likely the more generations of copies are made.

How long does key cutting take?

Key cutting is typically a quick process. It can only take 1 to 2 minutes to cut a standard house key while you wait, but more intricate keys and fobs can take up to an hour. Your key cutter will let you know how long the process is likely to take so you can decide if you want to return later.

If you need mobile key cutting or an emergency locksmith, their response time will depend on how far they are from your location. Most local locksmiths can arrive on your site within 30 minutes to 1 hour.

How much does key cutting cost?

Key duplicating is generally inexpensive, with prices starting as low as $4 - $5 for standard house keys, but this depends on the type of keys and other factors. After hours key cutters or emergency locksmiths will charge an additional call out fee.

As a rough guide, you can expect to pay in the area of:

• Standard house keys: $4 - $20
• Standard car keys: $8 - $10
• Electronic systems and lockboxes: $40 - $550

What other services do locksmiths provide?

If you're using a locksmith for key cutting, they may be able to provide other services you need at the same time related to locks, keys and security, such as:

• Supplying and fitting new locks for a home or business premises
• Replacing faulty keys and locks
• Opening homes, cars and business premises if the keys have been lost or stolen
• Replacing car transponders that have been lost or stolen
• Advising you about other security risks and solutions

How to choose the right key cutting professional 

Key cutting is a skilled trade, so you need to be confident that your key is being made by a qualified and experienced professional. Some things to check are:

• Does the locksmith have police clearance and a confidentiality policy?
• Are they licensed (if required in your state)?
• Do they guarantee that your house key or other key will work?
• Do they have positive customer reviews?

Handing over your keys to a stranger involves a level of risk and trust, so it's important to take the time to choose a key cutter you feel comfortable with.
