Fixed-Code RF Remotes Explained: How They Work and When to Use Them

What is a Fixed-Code RF Remote?

A fixed-code RF remote transmits the same code value every time a button is pressed. The code is pre-programmed at the factory and stored in both the remote and the receiver. When you press button A, the remote always sends “code A” – exactly the same value every time.

How Fixed-Code Works

1. Code storage: Each button has a fixed numerical code stored in ROM/EEPROM
2. Transmission: Press button -> send code via RF (315/433/868 MHz)
3. Reception: Receiver compares code with stored value
4. Action: If match -> activate relay / motor

Common Fixed-Code Frequencies

• 315 MHz: US, Canada, Mexico (LiftMaster, Chamberlain, Genie)
• 433.92 MHz: EU, Russia, CIS, Australia, NZ (most brands)
• 868 MHz: EU (newer European installations)

Security Comparison

• Fixed-code: Low (code can be captured with RF sniffer)
• Rolling-code: High (code changes every press, impossible to replay)

When to Use Fixed-Code

• Budget applications (basic gates, sheds, simple garage doors)
• Older installations (pre-2000 systems)
• Multi-remote consolidation (universal 4-band cloners)
• Backup remote (cost-effective replacement)
