Cant remember security code

I recently disconnected my truck battery and when I reconnected it, the words "enter code" was flashing on the head unit. I tried every four digit series of numbers I could possibly think of but none of them worked. What do I do since I can't remember my security code?

PLEASE CAN ANY BODY HELP I CHANGE MY BATTERY ON MY FORD FOCUS AND I CANT FIND MY CODE FOR MY SONY 6CD GENERATION 2


SECURITY CODE Most units incorporate a unique Key code security number that must be entered before the unit will operate. Normally, the Ford Dealer does this during the pre delivery inspection. If the battery is disconnected for any reason, or the audio unit is removed from the vehicle, the Key code must be re-entered before the unit will work again. LOST SECURITY CODE If you lose the Key code, contact your dealer and supply details of your audio unit along with some proof of identity. Your Dealer will then obtain the correct code from Ford Motor Company. ENTERING A SECURITY CODE If 'CODE - - - -', 'CODE 0000' or 'Enter Key code' appears in the display when you switch on the audio unit, you must enter the Key code using the station preset buttons.

Need radio code for 2006 suzuki FORENZA


A local dealer can help. They will have a code based on your VIN. Also, you can try this: The audio security system is activated whenever the audio system circuit is disconnected from the battery. A four-digit security code must be entered in order for the audio system to resume functioning. The security code is stamped on a card located in the vehicle (usually in the glove box). The following security code entering procedure must be used to deactivate the audio security system:
After connecting the audio security system to the battery, "CODE" will flash on the display.
Enter the proper security number into the unit, using the preset buttons No. 1 through 8.
For example, if the security number is "1234":
Press the preset button No. 1. "CODE" will disappear and "1 --- " will appear on the display.
Press the preset button No. 2, and "12 -- " will appear.
Press the preset button No. 3, and "123- " will appear.
Press the preset button No. 4, and "1234" will appear and flash three times.
The audio system will function and will transfer to the radio. If the incorrect security number is XXXXX into the unit, "Err" will appear followed by "CODE" and there will be several audible beeps. If this happens, repeat the security entering procedure beginning with Step 2.
If, after repeated entry of the wrong code, unit will enter "lockup" & will need to be repaired

Try disconneting the car battery and leaving it for about 30 minutes, then reconnect it and try again.

Be warned though that if your head unit has a security code, you will need to make a note of this before you disconnect the battery as you will be asked to re-enter it when you reconnect the battery.

Cant enter security


The unit cannot be used if you are not entering the correct security code and there is not a by-pass to the code.

My Kenwood KDC-MP232 entered "protect" mode, & I do't know why


This unit has an anti-theft program that is activated when a code is programed.

At this point forward, the power circuit is monitored, thus when the power is disconnected or drops below 12VDC it shuts down and the code must be entered to reactivate the unit and its functions.

Other circumstances that might trigger the anti-theft shut down are...

Bad power or ground connection to head unit.
A weak or faulty battery/alternator.
A blown fuse.
A sudden power surge, as happens when jump starting another car.

As for your personal 4 digit code, I cant help you with that but some high-end car audio dealers offer a diagnostic service that can reset a coded/locked out unit.

Good luck

'03 Honda Accord won't recognize CD player after battery replaced


I have a crv also. the audio system has an anti-theft mechanism, to deter thieves from stealing your cd player/radio. you need a code to turn your unit back on, usually a four or five digit code, that should have been provided when you bought the vehicle. If you don't have it, the unit will come back on after, and only after a full, uninterupted hour of driving.

Security lights flashing after battery cable removal-no start


Anytime you disconnect and reconnect your battery, the factory alarm will arm upon reconnection and the truck will not start. You have to close your doors, then manually lock and unlock the door with your key. This should turn off the security system and you should be able to start the truck.

Security code Lockout


I had a similar issue with a head unit in a newer Volkswagen. There was an unlock code burried in the vehicle's owners's manual.

Since your stero is an aftermarket model, I would bet the unlock code is in the manual for the head unit.
