Omega 449 01 Replacement Transmitter K9Mundialss Review

I recently bought a Nissan Frontier with an Omega R&D 449 car alarm but the key fob broke. I lost it almost 3 times. This new one synchronized easily with the instructions from the OEM website. A27 battery is included, already installed on the key fob for the program. NEW or USED Controller/Key Fob - With the engine running, turn the ignition on. Within 7 seconds of starting the engine, quickly press the service button 5 times to hear the alarm bellow notifying you that you are in programming…

To install, go under where the alarm button is, press the button three times, and then press each button on the remote control. You should hear an activation tone for each feature.

this item does not connect to my omega car alarm I have followed the instructions several times and even looked for it and tried different possibilities. It doesn't connect. Can I get help or advice on how to link it to work?

I give two stars because I still can't activate the remote control. Can someone please help me with videos or steps. I tried what was suggested and still couldn't activate the remote control. What is the valet button? Need help!
