Why erasing a JCM Go2 garage remote's memory almost never works

The garage remote that opens by itself and the reset button myth

A garage remote that transmits every six seconds with nobody pressing anything. The door goes up, stops, comes down, goes up again. And the owner is away from home, with the gate going haywire. That is the starting point of a query about a JCM Go2 transmitter that has lost its mind: it activates on its own, continuously, and not even changing the battery brings it back to square one. The question behind it seems simple enough: how do you erase the memory of a garage door remote so it can be registered again as if it came straight from the factory?

The short answer, the one nobody wants to hear, is that **most of these remotes have no reset button**. The code is stored on an integrated circuit, and there is no factory menu that resets it to zero. What does exist are reprogramming procedures against the receiver, and they only work if the transmitter is healthy. When the problem is the circuit itself, registering it again fixes nothing.

What happens when the remote activates on its own every six seconds

The symptom rules out the obvious. The button is not stuck: the light does not stay on, it blinks in cycles of about six seconds. There is no recent use that would explain the fault either, because the remote was stored away when it started transmitting on its own. That combination — periodic pulses, no physical contact and no history of use — points to **the board or a capacitor**, not the button membrane or the microswitch.

Anyone's first hypothesis is a jammed button or a worn-out membrane. It makes sense: it is the most common fault and the cheapest to diagnose. But the regular on-off pattern disproves it. A stuck contact does not produce a cadence; it produces a continuous or erratic signal with no rhythm. Here an internal timer is at work.

Can you erase the code from a JCM Go2 remote?

No, not from the remote itself. The programmed code is stored on an integrated circuit and **erasing it is practically impossible** without replacing the component. Transmitters of this type change their code randomly on each use — a rolling code system — but they keep the last one they sent on the chip. That memory is what stays recorded, and it cannot be wiped with a paperclip, a hidden button or a key combination.

There are receivers and transmitters with an internal reset button, accessible by opening the battery cover or through a pinhole activated with a clip. Others respond to holding both buttons down at the same time. These are real procedures, but not universal: they depend on the model and the manufacturer. In the case of the JCM Go2, the physical reset route is not documented as a solution to the stored code.

Reprogramming against the receiver: the only test left

Registering a new remote requires the transmitter to be blank, and that is the dead end. If the code cannot be erased, the alternative is to try programming it again against the receiver and see what happens. It is the acid test: if the remote repeats the fault after reprogramming, the diagnosis is confirmed and the circuit is faulty.

That is where the DIY options run out. The obvious recommendation is to throw it away and buy another one, but with two warnings that save money and headaches. First, **check frequency compatibility**: imported transmitters do not always operate on the band used by European receivers. Second, check whether the system uses fixed code or rolling code, because not every replacement remote works with any receiver.

Copying the remote or paying up

The quick and cheap route, when the original still responds, is to go to a shop that clones remotes. It costs more than a generic transmitter bought online, but it avoids the risk of incompatibility and trial and error. With a faulty remote that transmits on its own, that option gets complicated: there is no clean signal to clone.

The deeper question remains. How many of these transmitters end up in the bin over a capacitor worth a few cents? The industry does not make resetting easy, the manual does not cover it, and the user pays for the whole component. If the door opens by itself at three in the morning, the question is no longer how to erase it, but how long until it does it again.
