If you live in an area with extreme weather—like Phoenix in the summer or Buffalo in the winter—you’ll thoroughly enjoy equipping your Jeep with a VPA Remote Engine Starter (PN VIA-80272-C; $120) from Summit Racing. Depending on your model and onboard computer capability, you can even lock/unlock doors, lock/unlock trunks/hatches, locate your Jeep, kill its ignition or activate the parking lights and/or horn with its remote control.
The VPA Remote Engine Starter (with keyless entry) is a stand-alone system with three channels of operation. The kit includes everything you’ll need for the installation; i.e., two three-channel remote controls, wiring loom, relays, antennas and a manual with several different wiring diagrams. A word of caution, however: vehicles with an anti-theft system require a bypass module and T-harness, both of which are sold separately. This is not an easy installation and it is highly recommended that an experienced professional perform the installation to avoid any problems.
As I said above, extreme-weather locations can add to the pleasure of having one of these kits, because you can cool the interior down if it’s hot, or warm it up if it’s freezing outside. But if you live in more moderate climates, you can still enjoy the Remote Starter by surprising your friends or having the engine fully warmed up when you slip behind the wheel. One caveat, though, is to make sure the battery is disconnected or the remote controls are secured whenever you work on the engine. You also need to warn any mechanic that works on your vehicle once it’s installed, and the system is not recommended for vehicles with manual transmissions—you’d have to leave it neutral every time you park.
And you need not worry about a thief jumping in your vehicle and driving off while the engine is warming up. If the key isn’t in the ignition turned to on, when the shifter is put in drive the engine dies. In this 2005 Jeep, the key must be on and the brake pedal depressed to disengage the remote system’s safety features. You can also kill the engine with the remote control.
Another cautionary note I have is your starter. If the vehicle has over 50,000 miles on the odometer or if its mileage has accrued in severe conditions (i.e.: mud, dust, salt, etc.) I suggest replacing the starter at the same time. You wouldn’t want to trigger the remote and unknowingly cause the starter to clash, burn up, or lock on. You want the starter to work right every time. Replace the starter and then save the old starter just in case you and a friend might need it in the future.
