its not plug and play because the computer needs to recognize the new receiver. there is a series of unlock/locks you need to do if you don't have the push button start. you can try it yourself and if that doesn't work you will have to go to the dealer. the good thing is programming a new receiver should be cheaper than a new remote. I would try this sequence below, I have a push button so I don't know if this works or not or if doing the above incorrectly will further impact the fob use. but doesn't hurt to try:

1. drivers door open and unlocked. all other doors closed
2. key in / out. insert and then immediately remove
3. within 5 seconds press drivers door lock/ unlock switch in this sequence: lock,unlock,lock,unlock,lock,unlock
4. key in /out again
5. within 5 seconds repeat step 3
6. insert key
7. IGN on but don't start engine, then back to lock

the door locks should cycle lock then unlock to indicate the vehicle is in programming mode
within 40 seconds of that press lock and unlock on fob together for 1.5 seconds to 2 seconds the release
then press lock button for about 1 second

the door locks should cycle again. once means success twice means try step 2 again

to exit remove the key the doors will cycle lock then unlock to confirm you've left programming mode. test the fob
