Yes! This is a possible. However, you should be aware that it is far from safety. You can start the treadmill without using the key in a few different ways. However, you should be aware that none of them are completely infallible. And we don’t recommend trying any of these unless you don’t have another option or time to order a replacement safety key.

Before attempting to bypass the key, you should ensure that your treadmill’s console contains an emergency stop button. This is a fairly complicated concept, and one that should obviously be left to competent professionals. You might quickly burn out the motor if you don’t know what you’re doing.

Another tip for how to use a treadmill without a key involves using the key on another machine. Using the key from another machine of the same manufacture to bypass the key is a good concept, but only if another machine of the same remain available. If there isn’t, it could cause problems with your other equipment.

However, if you do not have another machine that is identical, this is not an option. We’re not sure if this would really work, but it’s worth a chance if you don’t have anything else to try first. This entails disassembling the safety key so that the electronic components can be used in another machine, such as a computer mouse.

In order to start a treadmill without a key, the final alternative is to go out and purchase a replacement key. Generally, replacement safety keys can be purchased from the manufacturer. Also, universal keys may be available, depending on the type of safety key you own. Treadmill safety keys are actually pretty inexpensive.
