Remote Keyless Entry With Au3 5b5 And W/o Au0

brjray · November 5, 2008

I have an 2008 Silverado LS with the RPO AU3 and 5B5. I have read document ID# 2196842 on techline that states that remote keyless is available by reflashing the RCDLR and BCM and purchasing keyless fobs. I called techline customer support center and they told me that my truck already has the RCDLR since I have tire pressure management system. So it was my thought that this would make it the same as the trucks that come with option AU0.

I want to have nstall the advanced 2 way remote start p/n 17802087 which is stated to add remote start to trucks with the AU0 option code that did not have nor were previously wired for remote start. The kit comes with the following per the GM techline installation manual:

Qty

Description

1

Remote Control Door Lock, 2-Way Remote Start & Info Display Receiver (2-Way RCDLR)

1

2-Way Remote Start and Door Lock Transmitter (With Information Display)

1

2-Way Remote Start, Door Lock & Info Display Antenna

1

2-Way Advanced Remote Start Owner Manual

1

Hood Latch

1

Hood Switch Wiring Harness

The only reason given by GM that this would not work was because I do not have option AU0 however techline confirmed that I have the RCDLR. Any techs out there know what would be missing from my truck that I could buy to get this to work? Again i want to know what specific part number is different so that I can buy it and intall it. I tried to attach as much of the info that I have read as possible. Thanks!!

Just a heads up to anyone with the same RPO codes. I had GM add keyless to my non keyless truck. They charged $50 for the VCI code and 0.5 hours labor. I got the fob for $49 at the dealer so all total was $141 after tax. I asked the tech if this would add the AU0 to my RPO list with my vin and he said that I should have a tech look it up after 1 month but he thought it should show up. This would mean after a month I may be able to add the Advanced Remote Starter kit w/lcd transmitter!
