Car starters?

Yeah you can it is simple enough to do just take the old care to the garage tell them you wanna take out the car starter and they will then bring the new in and they put it in that one

I have never used a remote starter, which seems to be what you want to take out of your old car and put into the new one.

If you have all the parts that were substituted when the starter was installed in the old car and the starter is compatible with the new car, then it should work.

yes you can

only one thing they are not east to wire into a car

Yes, but it is not usually done.
