How to protect Car & Garage Remotes stored outside
Between tradies on the move, holiday homeowners, and those of us that like to keep a spare remote in a secret outdoor spot, it’s common for Kiwis to store car or garage remotes outside.
And while it might seem harmless to leave a remote in a shed, under the car, or inside a toolbox, New Zealand’s extreme weather, temperature swings, and salty coastal air can take a real toll on these electronics over time.
At Remote Warehouse, we help Kiwis keep their remotes working longer with smart, affordable protection. Here's what to know about storing remotes outdoors – and how to avoid damage before it happens.
Why Outdoor Storage Can Damage Your Remote
Most garage remotes and car key shells aren’t designed to handle the elements. When stored outside or in vehicles long term, they’re exposed to:
-
Moisture and rain: Even in a sealed container, humidity or leaks can get in, causing corrosion or short-circuiting.
-
Sun damage: UV rays can crack, fade, or weaken plastic shells over time.
-
Heat exposure: Interiors of vehicles or metal storage boxes can get scorching hot, leading to warping or battery leaks.
-
Dust and grit: Job sites, farm vehicles, and beachside homes all bring fine particles that work their way into buttons and seams.
-
Cracked or ageing shells: Once the casing is compromised, internal components are far more vulnerable to the elements.
5 Ways to Protect Remotes Stored Outdoors
With a few simple habits and the right products, you can store your remote securely – even outside.
-
Upgrade the Shell
A new garage door remote case adds an extra layer of defence against moisture and impact. If your current remote is showing signs of wear, it’s worth upgrading the shell before it fails. -
Store in a Sealed Container or Key Hider
Whether you’re keeping a spare car key under the vehicle or leaving a garage remote for guests, use a proper lock box designed for storing keys and garage remotes, or a key hider that’s waterproof and tamper-resistant. -
Avoid Direct Sunlight
Store your remotes in shaded areas or away from windows inside vehicles. Prolonged UV exposure is one of the fastest ways to weaken plastic and reduce lifespan. -
Replace Shells and Batteries Regularly
Even with great storage, materials degrade over time. Proper remote key protection includes checking your shell’s condition and swapping out worn batteries to keep functionality strong. -
Keep a Backup
For work vehicles or shared garages, it’s smart to keep a spare remote stored indoors, just in case your outdoor unit fails.
When to Replace or Repair Your Remote Shell
If your remote is showing any of the following signs, it’s time to take action:
-
Buttons feel sticky or sunken
-
Plastic is cracked or brittle
-
Remote intermittently works (especially after rain)
-
You notice corrosion or rust in the battery area
In most cases, you don’t need a brand-new remote. Just replace the outer shell – no reprogramming required. It’s quick, cost-effective, and easy to do yourself with Remote Warehouse’s DIY Shell Replacement Guide.
Common Mistakes to Avoid
-
Using unsealed containers that let moisture in
-
Forgetting about backup remotes stored in vehicles or toolboxes
-
Delaying a shell replacement after signs of damage
-
Overlooking the battery – especially after long storage periods
