View CartCrimestopper has sold many aftermarket car alarm and remote start systems that used keyfobs with FCC ID CHX433TX. We know of more than a dozen such remotes, many of which are not interchangeable. Because they share an FCC ID, CHX433TX remotes should not be searched by the FCC ID. Instead, you should search either by the Crimestopper part number on the back of the remote or by the system brand and model number.
System brands for Crimestopper include popular systems such as Command Auto Shield and Cool Start, and less common brands such as EZ Start, Gargoyle, Informer, MX Vector, On-Guard, Pi, Rage, Samurai, SuperPage and SuperRage.
Some older Crimestopper remotes have been discontinued and are no longer made. In some cases, Remotes Unlimited still has some of the discontinued parts in stock. In other cases, the keyfobs are sold out and we do not expect to find a source for any replacements. For example, Crimestopper remote parts CS-382 and CS-383 have been discontinued for some time and RUI sold our last ones today.
