5 Ways to prevent a break-in through your garage

Five ways to prevent a garage break-in | New Zealand

Though burglary offences in New Zealand have declined slightly in the past few years, burglary and unlawful entry are still some of the most common crimes in the country, with more than 50,000 cases (affecting around 17% of households) in 2020 alone. 

Unfortunately, many thieves target garage doors as an entry point into your home. Due to most of us working from home or staying at home more since the onset of the pandemic, security may have become a little lax so perhaps it's time to reassess? Here are the top recommendations from our garage door specialists on preventing home break-ins through the garage. 


A garage door opener with anti-theft technology is a smart choice for homeowners.

1. Be smart about keys, remotes and openers

The first message on preventing a break-in really is to make it difficult for thieves. Choose a secure garage door opener with Tri-Tran+™ anti-theft technology. The code hopping technology generates a new random code with each use, preventing theft of your remote’s code.

Don’t leave spare remotes in the car glove box or console. In fact, don’t ever leave your keys or garage door remote in your vehicle. Be sure to secure remote controls with a strong keychain and take them with you. 

There are two ways you can avoid remote controls altogether. One of them is to install an entry keypad on the outside of the building, that allows you to open your garage door using a pin number. This is a handy option for families, eliminating the need for keeping track of remotes.

The other smart solution to disqualify remote controls and help prevent break-ins is Garador’s smartphone control kit. Use the app to operate your garage door and provide many different access options to friends, family and couriers. Plus, you get notifications every time your garage door is used, from anywhere in the world*. *Subject to cellular and WiFi connection and availability.

2. Remove sources of temptation and easy access

Some would-be burglars commonly scout properties and come up with a plan before breaking in when the opportunity arises, while others are total opportunists. Try taking a look at your garage through the eyes of a thief and see where the security weaknesses lie. 

Does your garage have windows? Ensure they are locked when you’re not at home. Consider adding curtains or a privacy film to block out prying eyes. 

Are there tools lying around? Hammers, mallets and even spades could be used to force entry. Tidy away any supports or ladders that could be used to gain access to windows and other weak points.

Trim bushes that could be used as hiding spots and clear away piles of plant trimmings or rubble near the garage and house.

Tip: It’s also a good idea to be mindful of how long your garage door stays open. To minimise potentially prying eyes, it’s best not to leave your garage open unnecessarily.

3. Block the cord

Most Garage door openers have manual release cords to allow for manual door operation in case of an emergency or power failure. In some cases, it may be possible for a burglar to hook the cord through the tiny crack between the trim and the top of the garage door, pull the cord and gain access to your garage. Take a look at your manual release cord and if it’s close to the entrance, screwing a small steel plate to the belt can block the cord from outside threats.


Garages left open to expose their contents provide a window-shopping experience for thieves.

4. Lock doors and add interior padlocks

Reminding you to lock your doors sounds like a no-brainer but up to 40% of burglaries are committed without the thief even needing to break in. If your garage has an access door other than the garage door, keep it locked and don’t leave spare keys in an obvious place.

Padlocks are another smart way to protect your garage from break-ins, especially when you’re away from home for an extended period. Hinder thieves by attaching padlocks to the tracks above the rollers. This may require drilling, but your garage doors won’t budge when you’re away on holiday. Simply remove the locks when you’re ready to use the door again.

5. Invest in routine maintenance

In addition to all these practical steps to prevent a garage break-in, it’s also important to prioritise regular maintenance for your garage door. Whether you have sectional, tilt, Flex-A-Door, or roller doors, professional maintenance is key. Garador’s service specialists can pick up on minor damage or faults that could leave your door vulnerable and offer practical advice on preventing break-ins and boosting security relevant to your situation.
