SOURCE: I have the same problem with my Daewoo Lanos

The transponder key has a chip in it.That is a programmed chip.But if this transponder key is not working then ,you will have to get the another transponder key,the other option is you can get the another key made from the local lock smith and then get the key programmed from the lock smith or from the dealer.Some lock smiths have the key programming device but if there is no lock smith in your area then you will have to get the key programmed with your dealer.Also you can try your preset key getting it re-programmed and check if it supports. ----------------- The exact procedure in which the transponder key works is as follows:---- Transponder key

Transponder keys may also be called "chip keys". Transponder keys are automotive ignition keys with signal-emitting circuits built inside. When the key is turned in the ignition cylinder, the car's computer transmits a radio signal to the transponder circuit. The circuit has no battery; it is energized by the radio signal itself. The circuit typically has a computer chip that is programmed to respond by sending a coded signal back to the car's computer. If the circuit does not respond or if the code is incorrect, the engine will not start. Many cars immobilize if the wrong key is used by intruders. Chip Keys successfully protect cars from theft in two ways: forcing the ignition cylinder won't start the car, and the keys are difficult to duplicate. This is why chip keys are popular in modern cars and help decrease car theft. Many people who have transponder keys are not aware of the fact because the circuit is hidden inside the plastic head of the key. THIS IS JUST FOR ADDITIONAL KNOWLEDGE ((((((On the other hand, General Motors produced what are known as VATS keys (Vehicle Anti-Theft System) during the 1990s, which are often erroneously believed to be transponders but actually use a simple resistor, which is visible in the blade of the key. If the value of the resistor is wrong, or the key is a normal key without a resistor, the circuit of the car's electrical system will not allow the engine to be started.)))))))))))))).

------------

This means that the programming of the Transponder Key has been corrupted or the Programming data of the Key in ECU ( Electric Control Unit ) has been lost or not responding. You now have to get a new Transponder Key. You can get it on E-bay for $30. After you receive it, reprogram the car to the New Transponder Key to the ECU By the lock smith or from the dealer.

Central locking not working on 2002 ford focus how do you programme chip


This vehicle is fitted with a transponder key type immobiliser. the indicator light is located on the centre of dash. It will blink when the ignition is switched off indicating system is armed. turning ignition on disarms the system. If the light remains on then a fault has been detected or the system did not recognise the key. Lock and unlock relay's could also be at fault and also power to these via fuseable links and fuses that are permantly live

Immobiliser is not turning off and not allowing the engine to start


is it a stick immobiliser?
If your vehicle does not start and the LED continues to flash while the Ignition is 'ON', this means that the Immobiliser system has not recognised the transponder stick.
Simply turn the Ignition 'OFF' then back 'ON' again. If the Status LED continues to flash, move the transponder stick closer to the key barrel until the LED stops flashing and turns 'OFF'.
If the transponder stick on the key ring does not disarm the immobiliser or the
transponder stick is misplaced, you can override the system by entering a 5-digit override number. Each vehicle has a unique 5-digit override number. This number is recorded on the
customer’s owner’s manual. If the customer loses their owner’s manual / override number, the number can be found by locating the vehicle’s Daewoo Stock Number (D.S.N). The customers override number is the last 5 digits of their D.S.N.

Overriding the system using the example 5 digit code 2,1,0,6,2
Important Note: 10 flashes of the Status LED represent the number ‘0’.
1. Remove the Transponder from the Key Ring.
2. With the system armed (LED flashing slowly) Turn the ignition ON/OFF 5 times, with the final position being off.
3. The LED will turn solid red for 2 seconds and then begin to flash.
4. When the LED flashes twice (2), turn the ignition ON. (number 2 was entered)
5. Turn the ignition OFF and wait for the LED to flash once (1) and then turn the ignition ON. (number 1 was entered)
6. Turn the ignition OFF and wait for the LED to flash ten (10) times and then turn the ignition ON. (number 0 was entered)
7. Turn the ignition OFF and wait for the LED to flash six (6) times and then turn the ignition ON. (number 6 was entered)
8. Turn the ignition OFF and wait for the LED to twice (2) and then turn the ignition ON.(number 2 was entered) The LED will turn solid red, which means the system is now overridden and the vehicle can be started. If an incorrect number is entered in, wait 11 flashes then start the procedure again.
NOTE: This is a one-event override. Once the ignition is turned off, the vehicle will passively immobilise after 30 seconds. If your 5 digit override number does not override the system, the chances are that you entered the wrong number. If this is the case, you’ll need to re-enter the override number
and try it again.

I have a code book and in the generic section it says transmission control system malfuntion. that might not be it but you could start checking that area.
