[header] How to buy a remote starter for an suv [title] Choose a single-or multiple-button starter [substeps] Single-button remote car starters function solely to start the suv when you're not in it. These starters are less expensive and inexpensive to have installed. Multiple-button car starters start your suv and can lock and unlock doors. 
Some multiple-button starters are equipped to turn on window defrosters and seat warmers. These are more expensive than single-button starters and are more prone to technical problems, but provide a higher level of convenience.
