Lost Your Garage Door Key? Here's Everything You Need to Know
Lost Your Garage Door Key? Do Not Panic
Your garage door key may be small, but its importance is easy to underestimate - until it goes missing. Losing it can mean losing access to your vehicle, tools, and any valuables stored inside. The good news is that replacement options are straightforward, and a locksmith can usually resolve the situation the same day.
Types of Garage Door Keys
Before sourcing a replacement, it helps to know which type of key your garage uses.
Tubular Keys
The most common type of garage door key in the UK. They have a hollow, cylindrical barrel and are typically made of brass or nickel. Many hardware shops and locksmiths can cut these, provided they can identify the brand.
Sidewinder Keys
These feature a distinctive wavy pattern cut into the edge of the key blade. Less common than tubular keys, but locksmiths with the right equipment can cut duplicates.
How to Find the Right Replacement Key
If You Know the Brand and Model
Check the lock barrel for a manufacturer name or model number. With this information, you can:
- Search for a compatible replacement key online (ensure you buy from a reputable supplier)
- Visit a hardware shop or locksmith who stocks that brand
If You Do Not Know the Details
A locksmith can inspect the lock, identify the key type, and cut a replacement on-site. This is often the quickest and most reliable route.
Getting a Spare Key Cut
If you have a working garage door key, get a spare cut without delay - it costs very little and will save you considerable hassle in future. Most hardware shops and locksmiths can duplicate tubular and sidewinder keys at a cost of £5-£15 per key.
Rekeying Your Garage Door Lock
Rekeying changes the internal pin configuration of your lock so that only a new key will operate it. This is the right choice if:
- You have lost a key and are concerned it may be in the wrong hands
- You have moved into a property and do not know how many keys were previously cut
- You want to consolidate multiple locks to work on a single key
A locksmith will typically charge £50-£100 for a rekey, depending on the lock type. This is almost always cheaper than a full lock replacement.
When to Replace the Entire Garage Door Lock
In some cases, replacement is the better option:
- You have lost your key and cannot source a replacement (discontinued lock model)
- The key is broken and lodged inside the lock
- The lock is old, worn, or damaged
- You suspect an unauthorised copy of your key exists
When selecting a new lock, choose one that is compatible with your existing door and has a good security rating.
Keeping Your Garage Door Keys Safe
- Always cut a spare and store it securely - with a trusted neighbour or in a key safe
- Do not leave keys in the garage door lock when unattended
- Consider a keyless entry system - keypad or remote-controlled garage door openers eliminate the problem of lost keys entirely
- If going on holiday, leave a spare with someone you trust rather than hiding it near the property
Troubleshooting Common Garage Key Problems
Key stuck in lock - Try wiggling gently while applying a small amount of lubricant (WD-40 or silicone spray). If it remains stuck, call a locksmith to avoid breaking the key.
Key broken inside lock - Do not attempt to force anything in further. A locksmith can extract the broken piece using specialist tools and cut a replacement.
Lock feels stiff - Regular lubrication prevents this. Apply graphite powder or silicone spray to the keyway annually.
