[caption id="attachment_9147" align="alignnone" width="640"] xr:d:DAFNhMbcd3k:193,j:36732004523,t:22093010[/caption] The SENTRY CODE HOPPING transmitters use an encryption technology known as KEELOQ, which is a secure protocol that is exceptionally resistant to grabbing and attempts at decryption. This protocol is also used by leading automobile manufacturers for remote keyless entry. The transmitters do not feature any user-settable dipswitches. The transmitters are “learnt” into an available memory slot of a compatible SENTRY receiver or SENTRY product equipped with a receiver. Due to the encrypted nature of these transmitters, it is not possible to learn them into receivers of other manufacturers, even though the same technology is used. RR-TX1SNCH
