Your garage door opener keeps a list of every remote it has ever been introduced to. It never shows you that list, and it never forgets on its own.
The Basic Mechanism
When a remote is paired to an opener, the opener stores it in memory. From then on that remote works. There is no expiry, no periodic re-authorisation, and no display showing what is stored.
The only way anything leaves that memory is if somebody deliberately clears it.
So the practical question is not “do I have my remotes” but “has anyone ever cleared this memory, and if not, what has been added to it since the opener was installed?”
For most houses, nobody has ever cleared it.
When It Actually Matters
You bought the house. The previous owner had remotes. So possibly did their adult children, a neighbour who fed the cat, a cleaner, a gardener, or a lodger from four years ago. All of those still open your garage today.
People are careful about changing locks when they move in. Almost nobody thinks about the garage, which on an attached house is a door into the property, often with an unlocked internal door behind it.
A tenant moved out. Same thing, and usually with less clarity about how many remotes existed in the first place.
You had building work done. A contractor given a remote for a six week job has no particular reason to think about returning it, and you have no particular reason to remember asking.
A remote was stolen from a car. Especially if the car was on the driveway of the garage it opens. That is a key taken from beside its own lock, and the thief knows exactly which door it belongs to.
A remote was simply lost. You do not know where. Somebody might.
The Fix Is Two Minutes
Nearly every opener has a learn or smart button on the motor unit, usually under a light cover. Holding it for a set time, typically around ten seconds until the indicator goes out, wipes every paired device.
Everything stops working at that point, including your own remotes, which is the intended behaviour. You then re-pair only the devices actually in your hand.
The exact button and timing vary, so check the manual for your model, or we will do it as part of any visit.
Do the Keypad Too
An exterior keypad has its own code and it is not covered by a memory wipe. Change it separately.
While you are at it, pick something that is not the house number, not a year, and not four identical digits. And if the keypad has visibly worn keys, change it periodically, because worn keys narrow a guess down a long way.
The Other Two Ways In
Clearing the memory closes the remote question. Two other routes are worth knowing about, because a reset alone does not touch either.
The emergency release cord. Every automatic door has one so it can be opened in a power cut. On a lot of doors it hangs within reach of the gap along the top, and a stiff wire with a hook can catch it from outside. That disconnects the opener and the door lifts by hand, in under a minute, with no damage left behind. A shield over the release stops it and costs very little.
Fixed-code openers. Anything from before the late 1990s transmits the same code every time, and a recorded code can be sent back later. Rolling code, which changes on every press, has been standard for a long time and fixes this. If your opener is that old it also predates the requirement for photo eyes, which is a stronger reason to replace it.
The Door Into the House
Worth saying plainly because it is the difference between losing a bicycle and losing everything else.
Most people leave the internal door between the garage and the house unlocked, because it feels like an interior door. It is not. It is the door that anyone who gets into the garage encounters next, out of sight of the street, at their leisure.
A deadbolt on it is the cheapest security upgrade available to you.
A Short Checklist
If you have moved house, had a tenant leave, or finished building work:
- Clear the opener memory and re-pair only the remotes you hold.
- Change the keypad code.
- Check whether the emergency release can be reached from outside.
- Fit a deadbolt on the door between the garage and the house.
- Take the spare remote out of any car that parks on the driveway.
The first two are free and take five minutes between them. The rest are inexpensive.

What a Reset Does Not Cover
Worth being clear about the limits, because a memory wipe gets talked about as though it solves everything.
It clears remotes and paired devices. It does nothing about the emergency release, nothing about a fixed-code opener still broadcasting a repeatable signal, and nothing about the internal door being unlocked. Those are three separate jobs and only the first is free.
It also does not cover anything wired directly. A wall button inside the garage is hard-wired rather than paired, so it is unaffected, which is correct behaviour but occasionally surprises people who expected everything to stop.
And it does not cover a keypad. Keypad codes live separately from the remote memory, so changing the code is a separate step that takes about thirty seconds and is skipped almost every time.
If You Are Renting Out the Property
Two habits worth building in, because this is where the problem repeats most.
Wipe the memory between tenancies as standard, the same way you would change a lock. It takes two minutes at a changeover when you are already there.
And prefer a keypad over handing out remotes. A remote is a permanent grant that relies on somebody remembering to return a small plastic object. A code is a temporary one you can retire the moment the tenancy ends, without chasing anyone.
