if the remotes worked previously then they may just need re syncing to the car,but if the fobs internal circut boards were from another car but have had a new blade cut and new chips coded it will start and run your but will not allow the remote part to open doors etc until it is coded the the car BCU.
To do this you need the keys barcodes. if you do not have those you can remove the keys circuit board out of the key, there should be a sticker with a bunch of numbers and letters (6?).
If you provide Marinabrian (forum member) with those numbers and ask nicely he may be able to give you the barcode for that key.
Still need a T4 session to code it to the car.
