In short: a Rademacher remote for the RolloPort garage door operators transmits, according to the manufacturer, on 433 MHz with rolling code. How to program a new one is described in the manual of your operator. A replacement has to match the model: Micro-Handsender for RolloPort S2 and SX5 DuoFern, Handsender 4385 for RolloPort S3 and S4. The 1Control catalogue lists no Rademacher remote as copyable. To open from your phone, the way is 1Control SOLO with the KIT: its receiver is wired to the push-button input of the operator.
Rademacher is a German brand (today DELTA DORE RADEMACHER GmbH); its website and catalogue are in German. The data comes from rademacher.de and the Rademacher catalogue 2026, read in November 2026.
Which Rademacher remotes exist: RolloPort S2, SX5 DuoFern, S3, S4 and S1
Rademacher currently lists two operators: RolloPort S2 (700 N) and RolloPort SX5 DuoFern (900 N), both supplied with two 2-channel Micro-Handsender remotes. For older operators the catalogue still lists the Handsender 4385. The table shows what Rademacher states and the result in the 1Control catalogue (10 November 2026).
| Remote | Fits (according to Rademacher) | Radio | 1Control |
|---|---|---|---|
| Micro-Handsender 2-Kanal (RP-MHS-RF63) | RolloPort S2 and SX5 DuoFern | 433 MHz, rolling code | Not in the catalogue: SOLO + KIT |
| Hand-/Wandsender 2-Kanal (RP-SX5-HS-RF11) | RolloPort S2, SX5 and SX5 DuoFern | 2 channels, KeeLoq encryption | Not in the catalogue: SOLO + KIT |
| Handsender 4385 (1 button) and 4385-4T (4 buttons) | RolloPort S3 and S4, RolloSystems T2, receiver 4340, rator 4300, rator 4310, rator f3 | 433.92 MHz, rolling code (KeeLoq) | Not in the catalogue: SOLO + KIT |
| RolloPort S1 remote | RolloPort S1 (no longer in the 2026 catalogue) | 433 MHz, rolling code (from the 1Control catalogue) | Cannot be copied: SOLO + KIT |
| rator 40 MHz | Older devices of the rator range | 40.685 MHz, fixed code (from the 1Control catalogue) | Not with SOLO or WHY; below 50 MHz QZERO is the product |
| DuoFern Handsender Standard (9491, 9491-2, 9491-5) | RolloPort SX5 DuoFern, through the DuoFern radio system | DuoFern | Not in the catalogue: SOLO + KIT |
Copying a Rademacher remote: what the catalogue says, and why SOLO + KIT
Whether a remote can be copied is decided by the 1Control catalogue, model by model. For Rademacher it has two entries. The RolloPort S1 remote (433 MHz, rolling code) cannot be copied to SOLO or to the WHY remote. The rator 40 MHz with fixed code transmits too low for both. Micro-Handsender, 4385 and DuoFern transmitters are not listed.
The way is SOLO KIT: a 433 MHz receiver with its own remote. The receiver is connected to the push-button input of the operator (in German: «Tastereingang»), like one more wall button; the cables are in the box. For RolloPort S2 and SX5 DuoFern, Rademacher states that an external push-button can be connected. The terminals are shown in the manual of the operator. SOLO then copies the KIT remote, and the door opens from the 1Control app. Your Rademacher remotes keep working as before.
- You can do it yourself: the receiver needs a 12 to 24 V supply. If you prefer not to open the operator, ask an electrician.
- Check first: look for your model in the SOLO compatibility checker for Rademacher. For the old 40 MHz remote, use the WHY and QZERO checker.
Remote not copyable? SOLO + KIT makes any gate smart
SOLO KIT wires to the push-button input of the motor and works with any automation: SOLO then opens from your phone even when the original remote cannot be copied. One-off purchase, no subscription.

Programming a Rademacher remote: what to look for in the RolloPort S2 and SX5 DuoFern manual
We do not reproduce the button sequence here: it differs from one operator to another, and only the manual of your model is binding. Rademacher publishes it in its Service-Center; the product pages of RolloPort S2 and RolloPort SX5 DuoFern lead there under «Bedienungsanleitungen» (operating manuals). To find the right place:
- Note the type of the operator. Rademacher lists the S2 as RP-S2-700N-6 (short) and RP-S2-700N-7 (long), and the SX5 DuoFern as RP-SX5DF-900N-5.
- Open the manual. Search for the type in the Rademacher Service-Center. According to the product page, the RolloPort S2 manual has the number VBD 543-1-1, and the one for the 4385 and 4385-4T remotes VBD 465-1.
- Read the chapter on remotes («Handsender»). It says which button on the operator starts learning, how the operator confirms, and how many remotes it stores.
- Look at deleting. Check whether a single remote can be deleted or only the whole memory. That decides what to do after a loss.
The SX5 DuoFern has two radio paths. The Micro-Handsender remotes use 433 MHz rolling code. DuoFern transmitters, such as the DuoFern Handsender Standard, are registered in the DuoFern system instead. For how learning works on other brands, see our gate remote programming guide.
Rademacher remote lost or broken: how to replace it
A replacement has to match the generation of the operator. The Rademacher catalogue 2026 lists these items:
- RolloPort S2 and SX5 DuoFern: Micro-Handsender 2-Kanal (item no. 8000 00 55) or Hand-/Wandsender 2-Kanal (8000 00 01).
- RolloPort S3, S4 and RolloSystems T2: Handsender 4385 with one button (8000 00 27) or 4385-4T with four buttons (8000 00 28).
- Access without a remote: Codierschaltgerät Funk (8000 00 02), with PIN entry.
A lost remote stays in memory until you delete it on the operator: the manual says how. A new remote changes nothing here, and SOLO + KIT does not touch the memory either.
If you have no working remote left, a copy is not possible anyway: it needs an original. SOLO + KIT does not, because the KIT brings its own remote, and after that you open from your phone.
Opening a Rademacher garage door from your phone: RADEMACHER app or 1Control SOLO
Rademacher itself states phone control for one operator only. According to the catalogue, the RolloPort SX5 DuoFern can be controlled by smartphone, tablet or PC when a photocell is used and together with the SmartHome Box. So you need the SmartHome Box as the hub and the RADEMACHER app. For the RolloPort S2 the product page mentions no smart home connection.
SOLO + KIT does not depend on the model. It fits any RolloPort with a push-button input, including an S1, S3 or S4:
- Nearby: SOLO opens over Bluetooth from the 1Control app, with no internet needed in the garage. It is rated IP66.
- For the family: you share access for free, at set times if you wish.
- From far away: you need the LINK hub. It talks to SOLO over Bluetooth and reaches the internet over 2.4 GHz Wi-Fi or Ethernet. With LINK, Alexa and Google Home work too; Siri works through Shortcuts.
Rademacher writes that the SX5 DuoFern must never be moved out of sight without an additional safety device such as a photocell. Keep to that with LINK as well. For a comparison of solutions across brands, see controlling your garage door from your phone.
Rademacher remote not responding: battery, range, memory
- Battery: according to Rademacher, the Micro-Handsender uses a 12 V battery, type 27A; the Codierschaltgerät uses two CR2032 cells. For the swap, see gate remote battery replacement.
- Range: Rademacher states up to 30 m for the Micro-Handsender. If the door only opens from very close, the battery is usually weak.
- A new remote is not accepted: first check that it matches the generation of the operator (table above). How many remotes the memory holds is in the manual.
- No remote opens any more: try the wall button. If the door does not move with that either, the fault is in the operator and not in the radio. SOLO is not a repair then; it is a job for an installer.
Frequently asked questions
How do I program a Rademacher remote?
By following the manual of your operator: it names the button to press, the confirmation and the number of remotes in memory. Rademacher publishes the manuals in its Service-Center.
Which remote fits the RolloPort S2 and SX5 DuoFern?
According to Rademacher, the Micro-Handsender 2-Kanal (RP-MHS-RF63) and the Hand-/Wandsender 2-Kanal (RP-SX5-HS-RF11). The 4385 and 4385-4T remotes are for RolloPort S3 and S4.
Can a Rademacher remote be copied?
The 1Control catalogue lists no Rademacher remote as copyable: the RolloPort S1 remote is not, and the other models are missing. With SOLO + KIT on the push-button input you still open from your phone.
Which battery does the Rademacher Micro-Handsender need?
Rademacher states a 12 V battery, type 27A. The Codierschaltgerät Funk runs on two CR2032 button cells.
Can I open my Rademacher garage door with my phone?
Yes. Rademacher states app control for the RolloPort SX5 DuoFern, with the SmartHome Box and a photocell. Whatever the model, 1Control SOLO + KIT works on the push-button input: over Bluetooth and, with the LINK hub, from far away too.
The bottom line
Start by noting the type of your operator and of your remote. For programming and deleting, follow the manual from the Rademacher Service-Center. If you want to open from your phone, look up your model in the compatibility checker and plan for SOLO + KIT: one connection to the push-button input, then Bluetooth from the app and, if you need it, LINK for opening from far away.
