What battery does my shutter remote take, and how do I change it?
Most Gaposa shutter remotes take one CR2032 coin cell; the Gaposa 16-channel takes a CR2450 and the Gaposa keypad two CR2032s. Somfy's Smoove wall remotes take a CR2032 and the Telis 16 two AAA cells. Open the back, slide the old cell out, fit the new one positive side up, and test the remote.
Key facts
- Gaposa's 1- and 5-channel handheld and on-wall remotes take one 3 V CR2032 cell, rated by Gaposa for about 2 years.
- The Gaposa 16-channel remote takes one CR2450, and the Gaposa wireless keypad takes two CR2032 cells.
- If the remote's lights do not come on when you press a button, the battery is the first suspect; Roll-A-Shield's battery-change videos end by testing the remote, with no re-pairing step. Roll-A-Shield data
- Gaposa warns that a keypad's radio range can be 25 to 30% shorter when its batteries are low.
- Gaposa remotes come standard on Roll-A-Shield remote shutters, a single-channel handheld unless you chose another style, and that standard remote takes a CR2032. Roll-A-Shield data
Applies to: Gaposa handheld, on-wall, 16-channel, key-fob and keypad remotes, and Somfy Telis, Smoove, Situo and Decorator RTS remotes, as supplied with rolling shutters including Roll-A-Shield's. SIMU's TSA+ is listed too.
Which battery does my remote take?
It depends on the brand and the model; the brand name is on the remote. Most Gaposa remotes take a CR2032.

| Gaposa 1-channel and 5-channel handhelds and on-wall remotes (Emitto line) | 1 x CR2032, 3 V |

Not every model is listed. For other models, such as the Somfy Telis 1 and Telis 4 handhelds, a Somfy key fob, a DecoFlex switch or an older remote, open it and read the code printed on the old cell, and buy the same one.
Gaposa rates its remotes and keypad for about 2 years per battery.
How do I know the battery is the problem?
Press a button and watch the remote's light. If it does not come on, the battery is likely dead. On a keypad, weak batteries can show up first as poor range: Gaposa says its keypad can lose 25 to 30% of its range on low batteries.
If the light comes on but the shutter does not move, the battery is probably fine. Check the channel and the motor instead: see a remote that a new battery did not fix.
How do I open a Gaposa handheld remote?
Release it from its holder and the battery is on the back.
- Flip the remote over and press the clip on the back to release it from the holder.
- With a small screwdriver or similar tool, gently push the cell down so it slides out.
- Push the new cell up into place, positive side up.
- Slide the remote back into the holder until it clicks firmly, and test it.
How do I open a Gaposa on-wall remote?
The transmitter lifts out of a wall plate behind a decorative frame.
- Remove the decorative plate around the remote. That exposes the mounting plate holding the transmitter.
- Gently pry the transmitter up off the wall plate and lift it out.
- Turn it over. Push the old cell down and out with a small screwdriver.
- Push the new cell up into place, positive side up.
- Press the transmitter back onto the wall plate until it snaps in, and refit the decorative plate.
How do I open a Gaposa deluxe or 16-channel remote?
Take off the back cover.
- Remove the back cover to reach the battery holder.
- Push the old cell down and out. The space is tight, so take your time and do not bend the metal contacts.
- Push the new cell in, positive side up (the 16-channel takes a CR2450).
- Refit the cover until it clicks.
Tip: On the 16-channel, do not hold the round (circle) button while the battery goes back in. That combination factory-resets the remote itself: hidden channels reappear and custom groups are deleted.
How do I change the battery in a Gaposa keypad?
The keypad comes off its wall plate first.
- Lift the top black cover with a screwdriver.
- Unscrew the keypad body from the back plate.
- Turn and unlock the battery cover and replace both CR2032 cells.
- Lock the battery cover, screw the body back onto the plate, lift the clear LED cover with a screwdriver, and press the black cover back on by hand.
Do not press the RESET button on the back while it is open. Holding it for 5 seconds returns the keypad to its factory settings. Code problems are covered on the keypad troubleshooting page.
How do I change the battery in a Somfy remote?
On the Somfy handheld in Roll-A-Shield's video, one small screw holds the back on.
- Turn the remote upside down and remove the small screw.
- Separate the back plate to expose the battery.
- Remove the dead battery and fit the new one.
- Refit the back plate and the screw, and test the remote.
A Telis 16 takes two AAA cells, and Somfy says not to use rechargeables in it.
Do I need to re-pair the remote afterwards?
Normally not. Gaposa keeps the paired remotes and the limits in the motor's memory, and Roll-A-Shield's battery-change videos go straight from the swap to testing the remote, with no re-pairing step. If the remote still does nothing after a fresh battery, check that the cell is the right way up and that the right channel is selected on a multi-channel remote, then follow the new-battery-didn't-fix-it page.
Replacement remotes are in the online store; to choose one, see which Gaposa remote you need. For help, call (480) 921-0200.

Frequently asked questions
Do I have to re-pair the remote after changing the battery?
Normally not. The pairing and the limits are stored in the motor, not the remote, and Roll-A-Shield's battery videos show no re-pairing step after the swap. One exception on the Gaposa 16-channel: holding its circle button while you put the battery back factory-resets the remote's own groups and hidden channels.
How long does a remote battery last?
Gaposa rates its remotes and keypad for about 2 years per battery, and SIMU says the same for its TSA+.
Can I use rechargeable batteries?
Not in a Telis 16, which Somfy says must not use rechargeable cells, or in a SIMU TSA+, which SIMU says not to recharge. Coin-cell remotes take the standard lithium cell listed for them.
I changed the battery and it still does not work. Now what?
Check the cell went in positive side up and that the right channel is selected on a multi-channel remote, then see the page on a remote that a new battery did not fix.
