fundamental questions about 2 or 3 button keyless entry
i just bought a used 2001 galant es. the local dealer said that it came with a two-button remote based on vin. the fcc id is hyq12aba. i noticed that there are 3-button one's in eBay with the same fcc id. there are also other 3-button ones with different fcc id: oucg8d-525m-a in eBay. following are my questions to those who have experiences:
1) can a 3-button one used for a 2-button function if they have the same fcc ids? (need diagram to figure out). mistu's part # mr490286, to mr587858 to mr587751. all have the same fcc ids HYQ12ABA.
2) can a different fcc id one be used? (i have no idea) when i open up my trunk, there is a wire connected to the lock. i suspect that the wiring of the keyless entry w/ or w/o alarm is the same. i could not imagine why they would make it different. the control modular may not be the same. hence, the third button may not function if it is not "connected" to the control modular. but, why there is a wire connected?
3) when the open buttun is pushed, all doors including trunk, are open. or the trunk door is not connected to the same buttun. is this the reason for the "trunck" button? otherwise, why there is a need of the trunk button, if all doors are open when pushing twice on the "open" button.
anyone's opinion is welcome.

I don't think there is keyless trunk release in 01 ES because that is what I have. I am using a two key remote I bought off E-Bay and it works fine after following the instructions.
Keyless Entry Fobs (FCC ID: HYQ12ABA vs. OUCG8D)
It is confusion to grab the right fob deal for the Galants from eBay. One seller claims that fob (FCC ID: HYQ12ABA) is good for 00 & 01 Model Year Galants, and another seller claims that fob (FCC ID: HYQ12ABA) is good for 00, 01, 02 & 03. A third seller claims fob (FCC ID: OUCG8D) is good for 02 & 03. Who is right or wrong?
I browsed the FCC ID search sites and found that FCC ID: HYQ12ABA was granted to Denso Corp. in 1995 and FCC ID: OUCG8D was documented for Omron Copr. in April 2001. This information implies that HYQ fobs are good for model yr. up to 01 and OUC fobs are good for model yr. 02 & up. Local dealers verified that my 01 Galant (Manuf. in May 2001) uses HYQ fobs. However, it doesn't mean that OUC fobs couldn't be used for the HYQ ones, if they transmitt the same signal frequency and coding to the receiver in the cars.
There are 2 (Lock & Unlock) or 3 buttons (Lock, Unlock & Panic) in HYQ fobs. There are also 2 (Lock & Unlock) or 3 buttons (Lock, Unlock plus Trunk or Panic) in OUC fobs. In fact, there are 7 submodels for the OUC fobs in according to FCC information. It appears that 02 model year have the Trunk button opition, while 01 model year doesn't have. If OUC and HYQ fobs transmitt the same signal and control coding, i.e. they are compatible, one would have more choices to grab fobs at a lower price from eBay. Whther the Trunk button works or not, it doesn't matter.
Can we start to gather these information by posting your model year, transmitter FCC ID and # or buttons on the fob of your car?

The link to the picture of the data link connector no longer works. Does anyone have a picture of it, so that I can make sure I'm connecting to the correct location and terminal #1.
Thanks
