Programming and safety
Use the programming instructions supplied by Chamberlain for this exact accessory. Compatibility does not mean every programming sequence is identical. If a remote used to work and suddenly stopped, first check its battery and the manufacturer troubleshooting steps before erasing opener memory.
If the opener is older than 1993, lacks working photoelectric safety sensors, or has been modified, consult the manufacturer before use. XEKOV does not provide instructions to bypass door safety devices or access controls. Use remotes only with systems you own or are authorized to operate.
Common questions
What openers does the Chamberlain MC100-P2 work with?
Its manufacturer-listed protocol coverage on XEKOV includes Security+ 2.0, Security+ 315 MHz, Security+ 390 MHz, Billion Code 390 MHz, Intellicode 315/390 MHz, MegaCode 318 MHz, SecureCode 310 MHz. Use the protocol table and exact opener examples on this page rather than matching by appearance.
Is the MC100-P2 a universal remote?
It has broad multi-brand protocol coverage, but universal still means only the published protocol list—not every opener.
Do I need the same number of buttons as my old remote?
No. Button count determines how many doors/functions the accessory can control; it does not by itself determine radio compatibility.
