My Lanos radio requires a code to unlock it whenever the battery is disconnected and reconnected. If I install a new radio, will it also require a code?


depends on the radio you bu. If the radio you get has a removable face then the code is stored in the face. If you get a radio that is all one part then it will have a code that you will have to enter every time the battery is removed. If the battery removal is something you do regularly then go to a battery supply shop and enquire about a back up pack that plugs into the data link and maintains all the electronic settings while the battery is out

FLAT batterY?? Battery OK,now? New one? Old one OK?HUH?
Get security codes FIRST: radio and NAV.
Disconnect battery from car and wait for 30 seconds and turn on the headlight switch,DURING the battery disconnect.
Turn off the headlights and reconnect the battery.
the security system should "re-boot" and be happy.
then there is the radio issue, Get the code.....

When you disconnect your battery and then reconnect itagain, it disables the radio. This is an anti-theft protection for your carradio.
The enable your radio the activation code is in your vehicle owner's manual. Ifyou do not have this code you need to go to your Nissan service centre andget them to enter this code for you.

I have a 1997 acrua battery died now radio is asking for a code


when power is diconnected from your car, the radio will ask for a code. this is part of the anti theft system of your car. inside your owners manuel case, there should be a slip with the code on it.( hope its there) input this into your radio. if its not allowing you, disconnect the battery, and reconnect. this should allow you to input the code sequence.

Bought a 2000 nubria daewoo and the seller did not give me the ra


You can obtain the code from daewoousa. Remove radio and get serial number from radio (white strip with black numbers on radio) Email this to daewoousa and they will email back your 4 digit code. To input code, disconnect the NEGATIVE battery cable, pause, then reconnect. Your radio face will now flash "code" Input the 4 digit code given to you. Radio will play after about 15 seconds.

Unless you Have AoolCodes DEALER IS A GOOD IDEA




Disconnecting/Connecting The Battery

Always stop the engine before disconnecting the battery negative lead and make sure the battery positive lead is isolated i.e. wrapped in a suitable cloth.

WARNING: Radio code saving devices must not be used when conducting work on air bag or fuel systems. It must be noted that, when using these devices, the vehicle electrical system is still live albeit with a reduced current flow.

NOTE: Before disconnecting the battery make sure that the radio receiver/cassette player/mini disc player and compact disc player keycodes are known and, that no data is required from the powertrain control module as battery disconnection will erase any fault codes and idle/drive values held in the Keep Alive Memory (KAM). It is not necessary to disconnect or remove electronic control modules.

Always disconnect the battery before commencing repair operations which require:
  • The vehicle to be jacked up
  • Work on the engine
  • Work underneath the vehicle
  • Arc welding
Alternatively a Radio Code Saver may be used. With the battery disconnected, a Radio Code Saver will allow sufficient current to pass to maintain the radio receiver/cassette player/mini disc player and compact disc player memory, operate the clock and supply the door operated interior lights while isolating the battery in the event of a short circuit.

Reconnecting the Battery

WARNING: If the battery has been on bench charge the cells may be giving off explosive hydrogen gas. Avoid creating sparks, and if in doubt cover the vent plugs or covers with a damp cloth.

Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or damage to sensitive electrical equipment.

Always reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the battery terminals are secure.

Restart the clock (where fitted) and set it to the correct time.

Re-enter the radio receiver/cassette player/mini disc player and compact disc player keycodes and preset' frequencies, if known.

Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature as the stored idle and drive values contained within the powertrain control module have been lost. Allow the vehicle to idle for a further three minutes . Drive the vehicle at constant speeds of approximately 48 km/h (30 mph), 64 km/h (40 mph), 80 km/h (50 mph), 96 km/h (60 mph) and 112 km/h (70 mph) for three minutes each. This may cause a driveability concern if the procedure is not carried out. This will allow the powertrain control module to relearn idle values.
