You step outside and your car is sitting there naked. The cover you paid good money for is just gone. Daniel Brooks has heard this story more times than he can count, and it’s always the same mistake: the cover was never actually locked down.
A car cover left loose on a driveway or street is an easy grab for anyone walking by. It takes seconds to pull off and resell. The fix isn’t complicated, but it does need the right hardware and the right technique.
Below, you’ll find exactly how to lock a cover in place, which lock type actually holds up, and where people go wrong.

A locking cable stops casual theft, not a determined thief with bolt cutters.
Can You Actually Lock a Car Cover to Your Car?
Yes. Most quality car covers include reinforced grommets or sewn-in loops along the bottom hem. You can lock a car cover using commonly available car cover lock kits, thread a cable through those loops, run it under the vehicle, and close it around a fixed structural point like a tow hook or wheel.
That anchors the cover to the car itself. Once it’s locked, lifting the cover off requires cutting the cable, not just pulling on the fabric.
⚠️ Warning
A locked cover is a deterrent, not a vault. A cover with an integrated cable lock cannot be removed without cutting the cable, but a determined thief with cutting tools can still get through it. Treat it as one layer of a bigger security plan.
How to Lock Your Car Cover Step by Step
The process is the same for most cable lock kits, whether they came with your cover or were bought separately. Here’s how to do it right.
🔢 Step-by-Step: Locking a Car Cover
-
1
Fit the cover first
Drape and align the cover fully before touching the cable. A loose fit makes locking pointless.
-
2
Thread the cable through the grommets
Pass the cable through each grommet or reinforced loop along the bottom hem for maximum security.
-
3
Run it under the car to an anchor point
Loop the cable around a tow hook, chassis point, or wheel. Skip anything that isn’t structural.
-
4
Position the lock out of easy reach
Put the padlock somewhere not easily accessible, such as under the car or near the ground.
-
✓
Close and store your key or code
Snap the padlock shut. Keep a spare key or written code somewhere safe, not in the glovebox.
✅ Tip
If the cable rests against a door or rocker panel, wrap that section in foam or a rubber sleeve first. Otherwise it will rub paint marks into the panel over time.
Which Cable and Lock Actually Hold Up?
Not every cable lock kit offers real protection. The cable thickness and lock body are what separate a genuine deterrent from a false sense of security.
This table shows what to look for when buying a cable lock kit.
A thick, vinyl-coated cable with a brass padlock handles casual theft and wind as a reliable first layer of security, but it will not stop someone with bolt cutters.

Extra Layers of Protection Beyond a Cable Lock
A cable lock is the core defense, but it works even better stacked with a few other habits.
📋 Ways to Back Up Your Cable Lock
-
Mark the cover: Engrave or mark the cover with your license plate number, name, or a unique symbol so it’s harder to resell. -
Add a motion alarm: Clip a motion-activated alarm to the cover so it triggers noise the moment someone lifts it. -
Park somewhere visible: A covered and locked car in a well-lit, visible area is a far less appealing target. -
Use the garage when you can: A closed garage door beats any lock a cover can offer.
What Most People Get Wrong About Locking a Car Cover
A few beliefs about cover security cause more stolen covers than the thieves themselves.
“Straps alone will keep it on.” Straps and buckles stop wind, not theft. Straps hold a cover in place, but only a lock and cable kit actually deters someone from taking it.
“Any cable will do.” A thin luggage-style cable snaps under bolt cutters in seconds. Cheap padlocks with thin shackles get cut quickly, so a thicker cable and brass padlock matter in higher-theft areas.
“The license plate number is the best marking.” A name on the front of the cover actually works better as a deterrent than a license plate number. It’s more visible and personal, which makes resale harder.
Locking your car cover down takes ten extra minutes and a $15-$30 cable kit. That’s a small price against replacing a $150-$400 cover. Get the fit right, thread the cable through every grommet, anchor it to something structural, and mark the cover with your name.
One thing to do right now: check whether your current cover even has grommets or loops for a cable. If it doesn’t, that’s the first gap to close before buying a lock kit.
Frequently Asked Questions
Can you lock a car cover onto your car?
Yes. Most covers have grommets or loops built into the hem. Thread a cable lock through them and around a structural anchor point on the car to secure the cover in place.
How can I prevent my car cover from being stolen?
Use a lock and cable kit, and mark the cover with your name. Together these make the cover both physically harder to remove and harder to resell.
Will a cable lock stop a determined thief?
No. A cable lock stops casual, opportunistic theft. Someone with bolt cutters can defeat most consumer cable locks in a couple of minutes if they’re specifically targeting your cover.
What size cable lock do I need for a car cover?
A 7 to 8 foot cable reaches under most sedans and SUVs from one side to the other. Wide trucks or full-size SUVs may need a longer cable, so measure first.
Can someone cut through a car cover instead of unlocking it?
Yes, a utility knife can cut the fabric around the grommets in a couple of minutes. Most opportunistic thieves avoid this though, since a cut cover can’t be resold intact.
What do I do if I lose my cable lock key?
For keyed locks, you’ll need to cut the cable with bolt cutters. Combination locks can’t be reset without the original code, so store a spare key or written code somewhere safe.
Do all car covers come with grommets for a lock?
No. Cheaper covers often skip reinforced grommets entirely. Check for them before buying a cable lock, since the lock has nothing solid to anchor to without them.
