Well I thought I would make out by buying two key fobs for my truck that were remote keyless entry and remote start off ebay since all I received was one keyless entry remote when I bought it. I have the AP8 RPO Code so the remote start "brain" is in there.

 

I went to the dealer and asked them to program the remote start fobs to my truck since the lights only flash when you hit the lock/start buttons. They said it did not work because I needed their $250 kit (+installation) that included 2-way remotes/antenna/upgraded items.

 

They had it in stock so I asked to see it, they opened the package and it was the two remotes by part number that I had in my hand and directions. Nothing else....so heres the kicker there is a printed authorization code on the instructions booklet and that is the only way I can install the remotes.

 

How do you get the remote start code without buying the $250 kit?

I think this is B.S. that GM puts the "brain" in the truck for remote start and you cant just turn it on.....you have to pay them the $250 + Labor $$. The dealer said they take that code and call GM who will then authorize that code rendering my truck usable through a TECH2 update.

 

Anybody have any experience with getting that auth code??

What are my options?

Also interested in this, my truck has the AP8 RPO.

 

ETA:

Here are my RPO Codes, with what I assume to be the code in question:

Most shops that can reflash Engine computers can turn the remote start function on or off. I usually charge about $100 to reflash a PCM. I may be wrong but I doubt you need anything more then that.

Dealer told me GM needs to be called, given the "Authorization number" That comes in the kit, which IMO is basically like a CD key for a computer game (Yes, I legally bought it, now I want my product to work please), GM rebuilds the RPO codes/adds remote start to list of factory options, and reflashes the computers with the rebuilt parameters. Until the computers are reflashed, the system doesn't know it has remote start. The dealer told me the remote start add ons were a PITA because more than one computer had to be reflashed.

 

Dunno how true that all is though, just dealer/tech talk while BSing about adding factory fogs, which they told me were a waste of money. Dealer said buy an aftermarket set and light bar instead. Go figure.

How do you know WHICH AP8 code ? I checked, and there are like 10 different AP8 codes

On my build sheet.. my Remote Start is code AP3.

 

Correct me if I am wrong, but I think:

 

AP3 is factory INSTALLED remote start

AP8 is Remote Start PREP package (Can be added later).

Only the dealer can install the remote start. You have to buy the remote start package from GM, and it

comes with two key fobs and instructions. The instructions have a unique code that comes with them & the

dealer has to use this key to get a special VIN specific code from GM. This GM code is then used by the tech

to activate and unlock the remote start in the BCM.

That is why you can't just buy the key fobs without the special code. GM will not give out the unlock code without

being given the one from the OEM package.

Once it is unlocked in the BCM you can then use any R/S key fob without having to go through this procedure again.

There are a lot of threads on the forum about this I would search through them.

 

The way I understand it is that authorization code allows the dealer to call GM, and get the software update to add remote start to your system.

 

AP3 I thought was the prep for the 2 way remote start system and the AP8 was prewire for basic remote start.

 

Maybe one of the dealer techs will chime in and clear this up.

Two-way remote? Mine are just the regular 3-button remote. Remotes don't beep or have a screen or anything, I believe they're only one-way. When I bought the truck, I actually got the dealer to throw in a second remote, as I was under the impression they come with two from the factory.. 2 keys, 2 fobs. The second one was brand new, apparently the remote star fobs are pricey..good thing they paid for it lol

I will have to see what's up when I get my truck. I was told that rather than order the PDD Exterior Plus Pkg. I could have the remote start added after the fact. The procedure described is the same as above. A price was mentioned, but I don't recall it. I guess I'll have to see if AP8 is on the glovebox door as it doesn't show up on the invoice or window sticker. Looking @ the 2011 brochure, neither option appears other than remote start is part of the LT Exterior Pkg.

Also comes in the AllStar packaage. 2011 allstar pack comes with fog lights, ez lift tailgate, tailgate lock, remote start, rear parking assist,int plus package (usb for radio, bluetooth, power driver seat etc) and towing package. Good deal. The 2011s with all star package have the same sticker price as my 2011 lt which has int plug package and hd towing package, but NOT the ext plug package.

I have remote start on my truck and the AP3 code. I Do Not have AP8 listed. I received 2 keys and 2 regular fobs (3 button no screen) at purchase. If I purchased the 2 way fob (with screen), would I have to do anything, besides the regular programming to my vehicle, to have the 2 way remote work fully? :rolleyes:

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.
