Frequently Asked Questions

Q: What types of remote controls can the 433MHz duplicator clone?

A: This 433MHz cloning key fob duplicator is compatible with most fixed code and standard learning code remotes, including those using IC chips such as 2260, 2262, PT2264, 1527, 2240, HT600, HT680, SMC918 series, and many more. It works with garage door remotes, gate remotes, alarm system remotes, and car remotes that operate at 433MHz frequency.

Q: Can it copy encrypted or rolling code remotes?

A: This duplicator supports fixed code and standard learning code protocols. Remotes using advanced encryption (such as encrypted HCS200 or HCS300 chips) cannot be successfully cloned. If you are unsure whether your remote uses a supported code type, please check the IC chip model on your original remote.

Q: How many remotes can I store on this key fob duplicator?

A: The 4-channel design allows you to clone and store signals from up to 4 different 433MHz remotes on a single device — ideal for managing a garage door, gate, alarm, and vehicle all from one compact fob.

Q: Does the 433MHz remote duplicator come with a battery?

A: Yes! The key fob comes pre-packaged with a 27A 12V battery, so it's ready to use straight out of the box. When the transmission range starts to decrease, simply replace the battery with a new 27A 12V cell.
