Steel Line HT4 Remote Features

The Steel Line BHT4 was the flagship keyring transmitter from 2013, for the Steel Line 303MHz range of garage door operators. The HT4 remote control has two buttons, which will allow you to code this remote control into two different door or gate openers. Featuring a rolling code encryption on 303MHz, the HT4 garage door remote will generate a new code each time the button is pressed from over millions of possibilities. This ensures that only your garage door remotes will ever open your gate or door, also preventing code grabbing devices from ‘replaying’ the code to open your garage door.


Programming the remote control yourself is very simple, taking less than 10 seconds. Our technical support team have created video guides as well as written step by step instructions to help you program in your Steel Line HT4 Remote.
