Marantec states that Synergy 260, 270, 280, 360, 370 and 380, M55 and Solo operate at 315 MHz, and its FAQ also identifies EOS M4500e, M4700e and M4900e at 315 MHz. Current Marantec 2-channel, 4-channel and micro remotes are 315 MHz accessories. Treat the opener model as a factory baseline, then verify the active receiver because an external or replacement receiver can override the original radio path. Older M4500, M4700 and Q-Line systems can use varying frequencies, so keep them conditional until receiver evidence is known.
What you are likely to notice
- You have a Synergy, M55/Solo or EOS e-series opener
- You need a current Marantec 315 MHz remote or keypad
- A working remote or receiver says 315 MHz
- An older M-Line/Q-Line opener has an unknown receiver frequency
Check these in order
1. Start with exact model, but call it a factory baseline
Marantec explicitly lists Synergy 260/270/280/360/370/380, M55 and Solo at 315 MHz, and separately identifies EOS M4500e/M4700e/M4900e at 315 MHz. That is strong factory evidence, not proof that a later external receiver was never added.
2. Let the active receiver outrank the opener model
If an external or replacement receiver is present, its label controls the handheld-radio path. A confirmed Marantec 315 MHz receiver supports current 315 MHz accessories even when the ceiling opener is older or another brand; a legacy receiver does not become 315 MHz because the opener model looks familiar.
3. Match the accessory to the verified 315 MHz path
Marantec's current #122436 2-channel, #122468 4-channel and #165095 micro remotes are 315 MHz multi-bit products. The #104053 wireless keyless entry is also 315 MHz. Choose the accessory format only after confirming the active receiver family.
4. Keep M4500, M4700 and Q-Line conditional until frequency is known
Marantec says these older families can use varying frequencies. Read the MHz imprint on a working remote or modular receiver rather than assuming the current 315 MHz family from the model name.
5. Route legacy 40/390/433 MHz evidence to the receiver-upgrade path
Current 315 MHz remotes are not a direct frequency match for a legacy receiver. Marantec documents external 315 MHz receiver upgrades for older radio systems, so the correct answer is a receiver migration path, not a forced 'compatible' result.
6. Do not treat 'universal' as proof
Marantec's U.S. FAQ explicitly warns that other-brand or generic universal remotes should not be assumed to work with the native Marantec radio system. Use manufacturer receiver/frequency evidence instead of appearance or button count.
Marantec makes frequency the first accessory filter
Marantec's own FAQ explicitly says operating frequency is the most important aspect of ordering wireless accessories. It lists Synergy 260, 270, 280, 360, 370 and 380, plus M55 and Solo, at 315 MHz. That manufacturer rule is more dependable than sorting remotes by housing shape or assuming every product sold as universal supports the native Marantec radio system.
For a known member of that family, a current Marantec 315 MHz remote is the correct research branch. For an older or unidentified opener, keep the answer unknown until a working remote, original manual, serial/model support record or modular receiver reveals the active frequency.
Choose two or four channels only after compatibility is established
Marantec's current #122436 two-channel and #122468 four-channel remotes both operate at 315 MHz. The channel count describes how many Marantec operators or compatible Marantec external devices the transmitter can control; it is not a different radio generation. The micro remote #165095 follows the same 315 MHz compatibility principle.
That means the buying order is simple: verify 315 MHz first, choose an official compatible transmitter second, then choose the form factor and number of channels that fit the household. Reversing that order encourages appearance-based guesses.
Why generic universal-remote claims need extra caution here
Marantec states that other brands or generic universal remotes should not be assumed to work with its native system. Treat that as a strong boundary. A third-party product needs its own explicit compatibility documentation for the exact Marantec radio family; a 315 MHz sticker alone is insufficient.
If the property already uses an external receiver from another manufacturer, document that receiver separately. In that modified installation the external receiver can create a new accessory path, but that does not change the native radio specification of the Marantec opener itself.
Stop DIY troubleshooting when…
- The active receiver/frequency cannot be identified
- The opener is an older M-Line/Q-Line unit and only the model name is known
- A ladder position is unsafe
- An external receiver has been added and its label is unreadable
Garage door springs, cables and a falling/unbalanced door can store or release dangerous force. Those are door-system problems, not just opener settings.
Common questions
What frequency does a Marantec Synergy 270 or 380 use?
Marantec lists both, along with the current Synergy 200/300 family, M55 and Solo, at 315 MHz.
Will any 315 MHz universal remote work?
No. Marantec explicitly warns against assuming other-brand or universal remotes work with the native system. Verify an explicit compatibility statement for the exact product.
What is the difference between Marantec 2-channel and 4-channel remotes?
Both current versions use the documented 315 MHz system; channel count mainly changes how many supported operators/devices can be controlled.
How do I identify an older Marantec frequency?
Marantec recommends checking the MHz marking on a working remote, the original manual, or the modular receiver; serial/model support can also help.
