I am having trouble linking my Lynx 455 to my Tesla Model S Homelink. Is there a compatibility issue? Does the remote continue to send a signal with the button pressed?


The Model S uses a homelink system for the garage opener, and according to their compability list, the Lynx is not there. So Homelink does not guarantee the functionality of it. If you don't get it to work while following the correct procedures from Tesla, I recommend you get the universal receiver kit from homelink.com Note that there is a difference in transmitter frequency between US and EU universal kits, so make sure you get the correct one. good luck!

I have a Lynx system with a 5828 wireless keypad that I have connected a 5v transformer to it to keep the keypad lit always. The keypad does not stay lit always and it keeps going to sleep after 10...


It sounds like your 5V transformer isn't working. It could be the outlet it is plugged into isn't working, or the outlet is on a light switch that is turned off, or there is a problem with the keypad itself. The user manual says:

"AC-Powered Operation: When powered by the
optional AC adapter, the keypad remains active at all
times. If AC power is lost, the keypad reverts to
battery-powered operation until AC power is restored
On AC powered units you can get the status by viewing
the display."

The only way I know of to keep it active is by using the transformer.

Hope this helps.

Look for the control panel (Not the keypad unless it's a Lynx model). If it's not a Lynx, then the control panel will be in a beige metal box somewhere, usually in a closet, basement or other space. The model number is usually on a diagram inside the door.

I have an Automatice Doorman model 455 garage door opener. I recently changed the battery for its remote control. How do I reprogram the remote control?


Your opener is very old and not only are there no parts available but it is not a programmable system. Your best bet is to buy something more up to date which will be much safer to operate.

Hello does my lynx 455 plus sensors have lights


Not familiar with lynx but every sensor I have seen or heard of has a light. It is the only way to tell when they are pointed correctly at one another.
