Frequently Asked Questions

Is the remote pre-programmed or does it require setup before use?

Most remotes require programming to your opener before use. This process allows the remote to communicate securely with your specific garage or gate system.

If the product is listed as “compatible” rather than “genuine”, it will still need to be coded in the same way as your original remote.

Programming instructions are included with your order, and additional guides can be found on our Programming Instructions page or by contacting our support team for assistance.
