2005 x type security failed want start

SOURCE: 2001 daewoo lanos immobiliser problem car wont

Radio code has no bearing on the immobiliser at all.

Normally it is down to the key not recognised. Are you using the same / usual key as before? If not then try original or another key as it may be the transponder in the key you are using.

If same key or no joy then remove the lower Black plastic steering cowls on the column (normally 3 or 4 screws) you will expose the barrell assy, on the end of this you'll see the transponder pick up ring. Disconnect from loom, apply silicone grease to pins and reconnect then try starting.

If still no joy, disconnect positive terminal off the battery, touch the lead to an earth point for 2 to 3 seconds to defuse and reset ECU, reconnect and try again.

If still noy joy you will need a garage as special reading equipment is required.

Regards

Lloyd
