Electric door locks vs keyless remote door locks...Silverado

You may require a different BCM than the one the vehicle currently has. This
question is best directed to the GM Tech service dept.

First, what is a BCM?

Second, since OnStar is able to unlock my locks, why wouldn't just a
fob work?

Third, I contacted the dealer and they are willing to have a third
party install an after-market keyless remote at their costs. I have to
hand it to GM, they are trying. I didn't even bitch, I just questioned
the General Manager, damn he is a nice guy. I am just not sure I want
a after-market put in.

Go to your dealer.
There is a combo of cycling the key on and off between opening the door. The
locks will lock and unlock. If they don't, it will not work.
I'd bet key fobs will work though.

If you search the internet, you can find out how to set them, so you could
try it yourself.

In fact, you might be able to search this forum for the answer to how to set
it up.

I just searched this forum for Fobs, and found 42 hits.

If it didn't come with it you would need to have the BCM coding altered
and add the remote receiver module to make them remote operated. Best
bet is to ask the dealer about it, they MAY do it for a reasonable price
to make you happy.

Did you just buy the 2009 from a dealer?
If so, they should give you two key fobs.

Yes, I bought it from a dealer, brand new with 4 miles on it. The
service department says, according to the VIN #, I have keyless entry,
but according to the General Manager ( the guy that orders the
vehicles) says he didn't order keyless locks and the service
department is confused.

So, who do I believe? The owners manual isn't much help because they
talk in generalities. They talk of Programing of the remote, but mine
don't have the electronic features of which they speak about in the
book. So, I am guessing the General Manager is correct in what he is
saying.

To make me happy, he offered to have another private company install
remote locks, but I am not sure I want "after market" items in my
electrical system.

It is not the type of thing I want to bitch about. I am just curious
as to my options.

Open the glove box. You will find a tag with the options that your truck
has on it. It will tell you if it has keyless remote locks. Look for
code 5B5, That is the option group (power locks, windows and mirrors)
that includes the keyless option on the extended and standard cabs, On
the crew cab model the remote keyless system is standard equipment.

As for aftermarket, I wouldn't myself. WAY to easy to screw up many of
the current electronics in a vehicle.

As for the OnStar unlock, that is an integrated function of the Body
Control Module (BCM) It has NOTHING to do with remote door locks. They
use the OnStar signal to trigger the same relay that you trigger with
the lock control switch.

I shouldn't admit this, but when I first read your reply to look in
the glove box for the 5B5 code, I thought you meant look thru all the
paperwork. After Agustus's reply, it hit me like a ton of bricks to
look for a tag in the glove compartment.

After looking at the tag, it lists many codes. It DOES list a 5B5
code. So, I ordered a fob online. We'll see how that works.

Thanks to all for helping me sort this shit out. I am always amazed at
the knowledge and info found on here. Most can't be found locally. You
guys are GREAT!

Most alarm companies butcher the wire harness. They use cheap connectors to
"tap" into existing wiring. My experience with them is not good. You would
be wise to find a different solution.

I would go to the dealer. Borrow a FOB from a different truck and see if you
can go through the programming instructions and get it to work.

Just because the truck has electric locks doesn't not signify that it
has remote entry.

For a remote to work, a receiver must be installed in the vehicle.

Copy down your V.I.N. and call your favorite dealer - call the parts
department.  Ask the parts person to decode your V.I.N. to see if you
do or do not have the remote entry option.  If the truck is equipped
with the receiver, it's just a matter of purchasing a remote and
programming it to the vehicle.

Most trucks have an easy programming procedure that is outlined in the
user's manual.

Good Luck!

Apparently actual conversations with the dealer did not elicit a good answer
for him.

 

I'll try to explain this better. The first thing I did was call the
dealers service department. They ran the VIN and said I have keyless
entry. I then spoke with the General manager about getting the fobs to
operate it. The General Manager said it DID NOT have keyless entry and
he knows it doesn't because he was the one who ordered this truck.

After reading the owners manual on "how to program the keyless entry",
I couldn't find the DIC (Drivers Information Console (yes, that's what
they call it)) that the book relates to on my truck. Nor could I find
how to program the fob without a DIC. Sounds funny huh?

Anyway, I found the fobs on eBay for $20 + shipping. I'll probably buy
one and check it out. If it don't work, I will resale it.

It just confuses me that OnStar can open my doors without a key, but I
can't. You would think that if a vehicle has OnStar, it would have the
necessary equipment to add a Fob.

Thanks to ALL

The commercials have an Onstar operator unlocking a truck
for a guy who left his keys in. Or some kind of car. There
has to be a link, somehow.

Yes, OnStar can operate the locks, but a key-less recevier may or may
not. It can depend on the software in the Body Control Module. Also,
the BCM  may not have a receiver (wire-less) for the keyfob. It may be
a totally different BCM / receiver system for wire-less locks, or not.
 
The dealer (or if you don't trust YOUR dealer, ask another can find
out. You will need the VIN and if you have it the build sheet. Just go
ask.

YES, ONSTAR can operate the locks, thet there may not be "keyless"
entry on that particular vehicle.
 
ONSTAR would be wired directly in to the locks, or, the buss that
controls them. It wouldn't need to be "wireless" or "keyless'.

The DIC is not necessary to program fobs. It just makes it easier to enter
programming mode if so equipped. A series of actions involving the ignition
key and the power doorlock button puts the BCM in to programming mode and
then the fobs can be programmed. This only works if the the BCM has an RF
unit and is capable of programming. A vehicle ordered without keyless entry
will not have this BCM. As was pointed out by another poster, check you
glove box for the RPO code applicable.

Here's the latest and probably the final.

I purchased a fob from online. I tookit to the dealer to see if they
could program it since my truck don't have the Driver Information
Console ( DIC for short). The service manager originally checked my
VIN and stated that it DID have keyless remote. But, since then she
investigated and found out that it didn't because of the Package that
included the doorlocks, powerwindows and mirrors.

Anyway, she had a service tech try to program it. He stated he was
unable to access the area which needed to be accessed. So, I guess the
only way for me to get keyless remote is to have it installed by an
aftermarket business. This won't be done because I don't want them to
cut into the original factory wiring.

The General Manager said he would pay for the aftermarket if I wanted
it. I appreciated his attempt to please me. It is not that big a deal
for me to use a key, so I will keep it like it is.

After I had purchased the truck and the salesman was putting on my
tags and filling the tank, the General manager came outside and we
talked a little (before the keyless entry dilema), I told him I liked
the looks of the plastic chorme wheel covers better than the Alloy,
even tho they cost much less. He then offered me a complete set of
brand new tires and chrome rims for free. He had taken them off
another truck because the buyer didn't want them. Somehow he worked it
into the deal. ya gotta like that!

So...........Thanks to all for your help.

Hank <~~~~really isn't too lazy to open the locks with a key  :-)
