Is the key cut? I am not sure if it's the same for the MDX but here is the instruction for programming the 2nd generation TL key

1...your new key
2...a MASTER KEY (one with the remote in it)already programmed to car.
to program the transponder- (thats the immobilizer part)
sitting in dr. seat, put the master key in ignition, and turn to on.engine OFF. press the gas pedal 5 times to floor and release. now press brake 6 times (press and release)
remove master key from ignition. install new key and turn to on...engine off. press gas to floor once. now wait. the security light will blink for about 45-60 seconds, then it will go off if you did it correctly. once the light is off, car should start.

For the remote part. in drivers seat WITH DOOR OPEN. start with door unlocked. first put master key in ignition, turn to on, then back off and remove. using the lock/unlock button on drivers door. press lock.. then unlock 5 times.(lock,unlock,lock,unlock,lock,unlock,lock,un lock,lock,unlock)
Close drivers door, open drivers door.
Performe lock/unlock procedure again.
insert key in to ignition and turn to on, then back off and remove.(at this point the doors should lock and unlock by themselves ONCE)
Now press both lock and unlock buttons on REMOTE. release after about 1.5seconds. now press just the lock button on remote.
now open and close the drivers door a couple times to close programming. if you did it right, remote will now work.

I just bought a blank Acura key from amazon and took it to the Honda dealer who was nice enough to cut the key for me for free. He used a manual hand tool and had to call Acura to get the key code for the proper setting on the manual hand tool. used my registration to verify it was my car and also gave Acura dealer across town my VIN number in order to get right key code to cut the key.

I came home and tested the above method but it did not program my 04 MDX or shall I say copy over my "master" key's transponder chip information onto my new blank and cut key.

So for now I have an extra key that will lock and unlock door.

I noticed home depot will be able to cut and program key for you for the cost of the t5 key. They require you buy key first and then they will clone key with your master key.

I might go back and see if they will just clone the transponder info off my master and onto my new cut key. Wish me luck.

I bought a blank T5 key for $10 on ebay and had my Acura dealership cut and program it for free. They just needed my original key to duplicate it on the blanks. Dealership told me they would cut and program first generation MDX keys for free. They only charge for second generation keys.
