This is a question that many truck owners ask themselves. After all, a tonneau cover is an investment, and you want to make sure that your investment is secure.
There are a few things to consider when determining if a tonneau cover is secure.
Are Tonneau Covers Secure?
First, consider the material of the cover. Some covers are made from heavier-duty materials than others. If security is a concern, opt for a cover made from a material such as aluminum.
Another thing to consider is the locking mechanism of the cover. Some covers have built-in locks, while others do not. If security is a concern, opt for a cover with a built-in lock.
Lastly, consider where you will be storing your truck when it is not in use. If you will be storing your truck in a garage or other secure location, then security is less of a concern. However, if you will be storing your truck in an unprotected area, then security becomes more of a concern.

Are Tonneau Covers Easy to Break Into?

In general, tonneau covers are not easy to break into. However, there are a few things to consider that can make a cover more susceptible to break-ins.
First, as mentioned above, consider the material of the cover.
Obviously, soft covers are easier to cut through than hard covers, so if you’re going to be storing expensive items inside, always opt for a hard cover.
Second, consider the locking mechanism of the cover.
As mentioned above, some covers come with built-in locks, while others do not. If you choose a cover without a built-in lock, you can always add your own aftermarket lock to the cover.
Lastly, consider where you will be storing your truck when it is not in use. If you will be storing your truck in an unprotected area, then security becomes more of a concern.
Adding a security system to your truck, such as an alarm or GPS tracker, can also help deter would-be thieves.
Are Roll-Up Tonneau Covers Secure?

Roll-up tonneau covers, also known as soft covers, are generally secure. For obvious reasons, they are not as secure as their hard cover counterparts, but they still do a fantastic job at protecting your gear.
Soft cover and roll-up covers usually cost much less than hard covers, so it’s understandable why many people choose this option. They are also often better at handling winter conditions as they don’t get stuck from ice build-up like hard and retractable covers sometimes do.
But if you are trying to protect really expensive gear, a hard cover is the way forward.
Can you break into Bakflip MX4?

The Bakflip MX4 is a hard folding tonneau cover that is made from aluminum. It has a built-in locking system that consists of two locks, one on each side of the truck bed.
The Bakflip MX4 is considered to be one of the more secure tonneau covers on the market.
However, nothing is impossible to break into and the MX4 is no exception. With little effort, a thief would be able to pry open the cover with a coat hanger for instance. However, this is not a slight on the MX4, as most tonneau covers are the same.
Despite all of this, it is far more secure than a soft cover due to the fact it looks tough to break into, wheras a fabric cover looks easy to cut through (and is).
So while the MX4 isn’t that difficult to break into if someone tried, its appearance is a deterrent for most.
