Looking to put remote start on my 05 trailblazer. It is a "sport" model with factory security and door locks. Suggestions???
The vehicle has the Passlock2 immobilizer system. There are many ways to bypass that including the "relays & resistor" method.
If you want to control the power locks from the new remote start units' FOB's and put the factory ones aside ( they will still work ),
get a remote start / keyless entry unit.
If you want to make the install easy get a full featured bypass module that handles the Passlock2, locks and factory alarm.
Depending on your budget and technical ability, you could get a one way, one button remote start unit and use the relays & resistor method
to bypass the Passlock2 for $50. At the other end of the scale would be a long range, two way, system with keyless entry and a full
function bypass module for about $250. This assumes you are satisfied with you Factory Alarm and don't want to add to it.
The middle of the road suggestion for a DIY'er would be an Ultra Start U1272 remote start w/keyless entry unit and an iDatalink ADS ALSL GM1
bypass module. Cost is about $100. This would give you an easy to install, easy to program ( with no special programmers ), quality unit with 2 one way remotes
that have over 1,000 feet of range and a very reliable Data type Passlock2 bypass module with only one connection to the vehicle and easy
programming..
Making a recommendation is tough, as there are many good products out there. As a DIY project, you would need basic automotive hand tools,
a soldering gun, and a Digital Multi Meter. On a scale of 1 to 5, with 5 being the hardest, it's a 4. That's because there is a lot of info must be
gathered and put to use. Additionally, you are integrating an aftermarket unit into a vehicle. Any mistakes could be serious and costly. The
important items are the availability and ability to use a soldering gun and a Digital Multi Meter.
