I have a 2001 dodge ram, how do I know if it's capable of having a keyless entry?

If the window is down then it's a keyless entry.

 

Replace the Remote Keyless Entry (RKE)
transmitter batteries. (Refer to 8 - ELECTRICAL/
POWER LOCKS/REMOTE KEYLESS ENTRY
TRANSMITTER - STANDARD PROCEDURE - RKE
TRANSMITTER BATTERIES). Test each of the RKE
transmitter functions. If OK, discard the faulty batteries.
If not OK, go to Step 2.
(2) Program the suspect RKE transmitter and
another known good transmitter into the RKE
receiver. (Refer to 8 - ELECTRICAL/POWER
LOCKS/REMOTE KEYLESS ENTRY TRANSMITTER
- STANDARD PROCEDURE - RKE TRANSMITTER
PROGRAMMING).
(3) Test the RKE system operation with both
transmitters. If both transmitters fail to operate the
power lock system, a DRBIIIt scan tool is required
for further diagnosis of the RKE system. Refer to the
appropriate diagnostic information. If the known
good RKE transmitter operates the power locks and

the suspect transmitter does not, replace the faulty
RKE transmitter.
NOTE: Be certain to perform the RKE Transmitter
Programming procedure again following this test.
This procedure will erase the access code of the
test transmitter from the RKE receiver.

I've never had a transmitter, I was just curious. Now, I do have another issue with my windows not going down in auxiliary. Have any ideas on that?

If auxiliary you mean key position #1 then no they will not work. The window motors are only powered up in key position #2, the run position.

 

You can buy a new transmitter for the locks and code it to the truck.

LOCKS/REMOTE KEYLESS ENTRY TRANSMITTER
- STANDARD PROCEDURE - RKE TRANSMITTER
PROGRAMMING).

 

I have a new transmitter, just not sure how to program. As for auxiliary, I mean when you turn the key back, as to just turn on the radio.

Windows, up-down, key position #2 only.

 

STANDARD PROCEDURE - RKE TRANSMITTER
PROGRAMMING
To program the Remote Keyless Entry (RKE)
transmitter access codes into the RKE receiver in the
high-line or premium Central Timer Module (CTM)
requires the use of a DRBIIIt scan tool. Refer to the
appropriate diagnostic information.

 

Some up scale key and lock shops might be able to do it.

 

Fill out your signature line so we know the year of and equipment the truck has.

Where do I do that, I'm new. I tried to edit profile and it goes to change password
