Security keys are made to be used every day. They live on keychains, get tossed into bags, and sometimes end up on the floor. Whether you’re using a YubiKey, a Titan Security Key, or an iShield Key 2, the reality is the same: accidents happen.
Our security key covers are designed to protect your key during normal daily use, but no case is indestructible. The good news is that not all damage means the cover needs to be replaced.
Here’s how to tell what kind of damage you’re dealing with and what to do next.
Step One: Check if the Cover Is Still Functional
Before trying to fix anything, take a moment to inspect the cover.
Ask yourself:
Is the cover still doing its job?
A functional cover should:
-
Hold the security key securely
-
Allow full access to the USB or NFC area
-
Stay rigid enough to protect the key during use and transport
From here, damage usually falls into one of two categories.
If the Damage Affects Function
Functional damage means the cover is no longer protecting the key properly.
Examples include:
-
The cover feels loose or no longer grips the key
-
Cracks that reach structural areas
-
The connector no longer lines up correctly
-
Missing pieces or excessive flex
If this applies to your cover, don’t try to glue it right away.
Instead:
-
Take a clear photo of the damage
-
Reach out to our support team
-
Let us know what security key you’re using and how the cover is behaving
We can help you decide whether a repair makes sense or if replacement is the safer option. In some cases, attempting a repair could put the security key itself at risk, and that’s something we want to avoid.
If the Cover Is Still Functional and the Crack Is Small
If the cover still works as intended and the damage is limited to a small or partial crack, a simple repair may help extend its life.
One of the most effective methods uses thin super glue and capillary action.
Repairing Small Cracks With Thin Super Glue
Thin super glue (not gel) naturally flows into tight spaces. This effect, known as capillary action, allows the glue to seep into fine cracks and bond the plastic from the inside.
What You’ll Need
-
Thin, low-viscosity super glue (not gel!)
-
A clean and dry surface
-
A steady hand
How to Do It
-
Remove the security key and key ring
-
Make sure the cover is clean and completely dry
-
Gently align the cracked area so the edges meet naturally
-
Apply a very small amount of thin super glue near the crack
-
Let the glue wick into the crack on its own
-
Hold the area steady and allow the glue to fully cure
You only need a small amount of glue. Applying too much can cause mess, bonding where you don’t want it, or cosmetic issues.
Important Tips
-
Keep glue away from areas that directly contact the security key
-
Do not attempt this if the crack is large or still spreading
-
Allow full curing time before reinstalling the cover
This kind of repair won’t make the cover look brand new, but it can restore strength and prevent the crack from getting worse.
Not Sure Which Category You’re In?
If you’re unsure whether the damage is cosmetic or functional, it’s always better to ask first. A quick photo and message to support can save you time and help avoid further damage.
Security key covers are meant to be used, not treated like display pieces. Normal wear is expected. What matters most is keeping your security key protected and reliable when you need it.
