Aftermarket remotes of the DEI (Directed Electronics) manufacturer, going by many brands like Viper, Python, Valet, Avital, Sidewinder, have versions of this remote which are all compatible to replace each other. You can choose one that looks exactly like yours or one of the other ones shown and it will program to your system. The one important thing to note is to use the programming instructions of the original remote, not the one you are using as a replacement. For example if you get an Avital remote to replace a Valet remote, use the Valet instructions to do the programming, not the Avital instructions.,
