Key for my Suzuki Aerio 2003

Don't buy it from the dealer, just buy a used remote from eBay. Use these instructions to program it.

1. Confirm that all doors are closed and the ignition key is out of the ignition cylinder.
2. Open the driver's door.
3. Within 10 seconds, Insert key into ignition turn to ON position and back to OFF and remove the key.
4. Within 20 seconds, close and open the drivers door 3 times. (Drivers door should be open)
5. Within 10 seconds, insert key into ignition turn to ON position and back to OFF and remove the key.
6. Press and hold both the LOCK and UNLOCK buttons together on the same remote for at least 5 seconds, the doors will lock and unlock (that's a very good sign)
7. Within 5 seconds, press the LOCK button on the same remote and release. You just programmed your remote ??

You don't need to buy a remote from the dealer, you can buy one from ebay or Amazon for about $30, and you can program it yourself. The dealer will charge you $100 to program your remote. (Just remember on the last step make sure you press both the lock and unlock button at the same time).

The best way to go is to go to your local Suzuki dealer or to a locksmith as they can also reprogram keys.
