problem here is with a barrel for a lock , you need different keys to the rest of the vehicle go to a locksmith and buy the barrel and keys and have the barrel reset to the existing key that way you only have the one set of keys for the car and as the immobilizer is in the surrounds around the barrel it will not need reprogramming as you still are using the right key

How to add freon to a 2002 chevy malibu

If I remember right, the AC lines on GM are usually on the left side standing in front of the vehicle. Should be one big tubing and one smaller tubing. The big one is the suction line where you add the freon. You should find a plastic cap in the charging port. You need a can of freon and the proper snap on hose connection to fit the big tubing. Some recharge kits have the hose and a pressure gauge attached so you can watch how much freon you are adding. I recommend this type kit. You add freon with the car running and watch the gauge until the needle points to the green area. Watch removing the hoses since there will be some freon in the hose that could cause frost bit or skin burn whe removing it.
