Does a Daeoo Lanos 2002 have an immobiliser?

Unfortunately this is going to be an expensive fix. Most modern cars have electronics inside the key which communicates with the immobiliser system in the vehicle. This is what the 'Key Number' is for. It is specific to only your car as it is there to prevent the car being stolen.
You will need to replace the entire ignition barrel and contact a Mitsubishi dealer with your details to get the Key Number for your car. You will then need to buy new keys and have them coded to your car's immobiliser system using the Key Number.

Save a lot of money by calling a locksmith to make a new set of keys. A service call is way cheaper than replacing the column. I hope this helps. Take care.

go to a dealer with vin and proof of ownership and have them cut you new keys --or search and see if any locksmiths have the authorization to do same

A DEALER HAS TO DO THIS
TAKE CAR THERE THEY CAN CUT A KEY FROM THE VIN # AND REPROGRAM IT

Some locksmiths have the machinery to do this but you will have to shop around for them. The problem is that the new key has to be programmed to the immobiliser in the car so the dealer wants the car and the new key to complete the job.. When you consider that to have the job done on a lot of cars the job costs $25.00 for the key .$25.00 to have the key cut and $450 + to have it programmed I consider $200.00 to be reasonable

go to a dealer shop or good locksmith to make a new coded key

A Locksmith may be able to help you.

You cannot disable the immobiliser. If it were that easy, any car theif could defeat it by searching the internet. If you dont have any more master keys, you will have to have your local Toyota dealer reseed (reprogram) the immobiliser code, and program new keys for you. It should be about 2 hours labor and cost of keys, but only a dealer can do it. They need to use the Toyota scan tool, and access a Toyota only website with security codes.
