The compact fob weighs 0.068 kg and measures 14.33 in wide by 12.83 in high by 9.06 in deep, fitting easily on a key ring. Programming follows the printed steps and completes in minutes without additional tools. Buyers needing a single-button replacement or a dip-switch compatible unit should look elsewhere.

Questions about this item

What physical space is needed to mount the TX301 remote on a keyring or sun visor?

The TX301 measures 14.33in W x 12.83in H x 9.06in D and weighs 0.068 kg, so it fits easily on a standard keyring or clips to a sun visor without extra brackets.

How is the TX301 paired to a garage door opener, and what step is often missed?

Press the opener's learn button — purple, yellow, red, orange or green — then press a TX301 button within 30 seconds; the step often missed is releasing the learn button before pressing the remote button.

What maintenance will the TX301 need over time?

Replace the CR2032 coin cell when range drops below the rated 200 ft; no other serviceable parts are inside the sealed keychain housing.
