How do I get my nissan Altima to start automatically?

Bought a used ‘02 Nissan Altima SL from a Ford dealer. Clearly the play didn’t know that it had an involuntary start.

I was rowdiness around with the carry out as well as got it to begin though I do not know just how.

The keyless remote appears to be the batch Altima remote as well as has the follow buttons:

1. Door Lock
2. Door Unlock
3. Trunk unlock
4. Panic

(This is the indication - http://cgi.ebay.com/ebaymotors/2002-2003-2004-2005-NISSAN-ALTIMA-KEYLESS-REMOTE_W0QQcmdZViewItemQQcategoryZ33723QQihZ019QQitemZ290129579797QQrdZ1)

Holding buttons 1+2 together appears to toggle the automobile in between wordless as well as non-silent (horn beeps) locking of the car.

However, I have no idea how to involuntary begin the car. I’ve attempted land all opposite combinations of buttons though nothing.

Any ideas?
