The Forever Lock came out in 2014. It generated a lot of hype for being billed as “unpickable”. While the lock is next to impossible to pick, there are two documented ways to get in. Regardless, this is a fantastic lock.
Forever Lock says:
THE ORIGINAL HEAVY DUTY U-LOCK WITH THE ANTI-LOCK PICKING KEY LOADING CHAMBER! USE TO SECURE THE FRAME AND WHEELS OF YOUR BICYCLE OR EVEN THE TIRES OF YOUR MOTORCYCLE. THIS AWESOME LOCK PROVIDES A UNIQUE STYLE AND GREAT SECURITY!
Nobody would disagree with that statement. It seems as if Forever Lock has backed off the statement that it is “unpickable”, even though I would agree that it technically is unpickable. The reason for this is that you do not have direct access to the key way. As such, I won’t even bother talking about the pinning; however, if you are curious it is a dimple lock. The key itself will not be in your hand when opening the lock as the Forever uses a travelling key design. The lock comes with two keys and if you lose them, you are SOL.
It is difficult to describe how the locking mechanism works. It would be best to simply BosnianBill’s review below.
The body of the Forever Lock is hardened steel and resistant to any brute force attacks save for a circular saw. Ease of use is the only downfall here. Unlocking the Forever Lock is inherently an annoying process. However, the extra security is worth it.
These days we are seeing more bikes on the road, and some very expensive ones at that. There are some more expensive bike locks with poorer security features than the Forever Lock. That alone is reason to choose it over the competition when it comes to high end bike locks.
There are two documented vulnerabilities. The first is a bump key method. The second is a technique called “foiling” which has been around for years, but seems to be gaining popularity.The method uses a heavy gauge aluminum foil to grab and hold the pins at the shear line for the lock to be opened. Essentially, you are making a key impression while attempting to open the lock. While foil attacks are somewhat easy, for this lock, you will need a nonworking key. See below for DeviantOllam’s successful foil attack:
So the lock can be foiled, but is that cause for concern? It depends if you think that people would be wandering around with a nonworking Forever key and foil tape. Even if they are, it might take them some time to get the key into place. Your run of the mill bike thief is probably going to target cheap chain and cable locks instead.
As previously mentioned, this lock can also be bumped … which requires you to first make a bump key.
VERDICT: High security against any bike thief but the very motivated.
