1. • 1 Look in your owner's manual booklet for your radio anti-theft code. The code is printed on a small card (similar to a credit card) and included with your owner's manual. If you can find the code, skip to Step 5.
     If you cannot find the code, you'll need to retrieve it.
     
   • 2 Turn your ignition off to begin retrieving your radio code. Press and hold the "1" and "6" preset buttons on your radio. Turn your ignition on.
     
   • 3 Write down the code displayed on your radio. The display will flash with two numbers: one beginning with a "U" and one beginning with a "L." Write down both numbers (beginning with the "U" number), and then disregard the "U" and the "L."
     This number (eight digits) is your radio serial code. You'll need it to retrieve your radio anti-theft code.
     
   • 4 Contact Honda to retrieve your radio anti-theft code. You'll need your 17-digit Vehicle Identification Number, found beneath the driver's side of the windshield and your radio serial code. Honda's customer service number is (800) 999-1009. Provide the representative with the information to acquire your radio anti-theft code.
     You can also retrieve your radio anti-theft code online for free at https://radio-navicode.honda.com/
     
   • 5 Turn your ignition to "Acc" or "On" to power on your radio. Enter your radio anti-theft code using the preset buttons at the bottom of your radio. For example, if your anti-theft code is "55512," you would press the "5" button three times, then the "1" button, then the "2" button. This will unlock and reset your Honda radio.
     

This is the anti-theft device on your factory radio. When the battery died, the radio thought it had been removed from your car and went into anti-theft mode. When you turned the car back on, the radio should have read "CODE" on the display, at which point you need to enter the factory anti-theft code. After 3 failed attempts at entering the code, it will simply read "OFF" and the radio is locked.

At this point:
- find your factory anti-theft code - it should be in your owner's manual, or you can contact a dealer to retrieve it
- turn the key to the ACC position (radio and accessories on, but engine is off)
- turn on the radio so the display reads "OFF"
- let the car sit for 1 hour
- radio will turn off automatically and reset
- turn the radio on again, and it should read "CODE"
- enter the factory anti-theft code

Make sure you have the code before starting the procedure. To enter the code, use the radio preset buttons. For example, if your code is "4321", hit Preset #1 button four times, Preset #2 three times, Preset #3 two times, and Preset #4 one time. Then hit the "Tape" or "CD" button. Radio should now be unlocked.

Assuming you don't have the Anti-Theft Code and Serial Number that is found on the credit card sized Anti-Theft Radio Identification Card that comes with the vehicle at the time of purchase and is usually found in the glove compartment....

You have FREE options to retrieve that code by phone or on the internet BUT, the RADIO SERIAL NUMBER is REQUIRED (no matter what). (see bottom about removing ERROR E3)

4. Hold down the preset buttons 1 and 6 at the same time.
5. Turn the radio on while pressing down both the 1 and 6 buttons.(***IF your Honda doesn't have preset buttons on the radio then hold down the top part of the 'Seek/Skip' button AND the top part of the 'Change Disk' button instead.*** )
6. Write down the 4 numbers you see first and then 4 more that display. These eight numbers are the SERIAL NUMBER. This is NOT your CODE.
7. Make sure your VIN (Vehicle Identification Number) is handy to get the unlock code. (can be found on your insurance card, driver's side door jam, small plate on dashboard by registration and inspection stickers, etc)

* REMOVING ERROR E3

****If you entered too many wrong codes and got an ERROR E3 message displaying you'll need to do an additional step for even the correct unlock code to work.****

Disconnect your negative battery terminal (or pull the radio fuse out if that's easier for you) for 30 seconds then reconnect it and then the radio will say "CODE" again and you can put in your correct unlock code.

So what happened to begin with?

If the power from your battery to the Honda radio is interrupted the Anti-Theft feature kicks in, the radio is rendered inoperable and the screen reads 'CODE'. You must enter in the Anti-Theft Radio Unlock Code (usually 5 digits) to make it operational again. You know that much by now.

The BMW anti-theft radio circuitry is designed to essentially render your radio unsalable if it is stolen. If the radio is subsequently electrically reconnected, it will not operate until a five-digit security code assigned to your radio is entered. The anti-theft features and operation are as follows:

1. After the ignition key is removed, the red "anti-theft" LED will continuously flash, drawing attention to this feature.
2. Should anyone, such as a thief, touch any push-button on the radio after the key is removed, the anti-theft inscription will flash and a warning tone will sound for 5 minutes or until the ignition is turned ON .
3. Should the voltage supply to the radio drop below 5 volts due to a dead battery, electrical repairs, or radio removal (such as theft), the radio will not function when voltage is restored. The word "code" will show in the display only.
4. The proper 5-digit code shown on the TWO CARDS SUPPLIED TO YOU must then be entered (using the proper number radio push-button selectors in the bottom row) when the radio is on and the display shows "code". If the correct code is not entered in three successive tries , the radio will not accept entry until the radio has been left on for one hour with the ignition ON . IMPORTANT: When entering 5-digit code number, be sure to complete sequence number of that 5-digit code. For example: Code No. sequence is 43215 and you mistakenly enter 42 instead of 3, continue the code number sequence of 215 to complete that entry. The radio will not operate and "code" will reappear in the display. Re-enter the correct number sequence of 43215 and operation of the radio will continue. The likelihood of guessing the correct code is extremely remote. The radio is, therefore, unsalable to a thief. NOTE: If an audible beep is heard while entering the 5-digit code, STOP immediately ! Begin entering the code again, starting with the first number of the 5-digit code.
5. The code card should be placed in your wallet, or with the vehicle title papers for security as deemed necessary by your individual needs.
6. Should radio or electrical repairs become necessary, please give the repairing facility the radio code number. If you do not, only authorized BMW dealer personnel can obtain the code from BMW.
7. Should you lose your code cards, contact the nearest BMW dealer who will then obtain your code from BMW. You may be charged for removal of the radio to ascertain the radio chassis number.
8. WARNING: FOR YOUR PROTECTION, CODES WILL NOT BE GIVEN OUT TO ANYONE UNDER ANY CIRCUMSTANCES OTHER THAN AUTHORIZED BMW DEALER PERSONNEL AFTER PROOF OF VEHICLE OWNERSHIP AND PROPER IDENTIFICATION IS ESTABLISHED.
9. Install the 2 enclosed warning decals in accordance with motor vehicle regulations.

your owner manual tells you. Why not use the original code?

To change, here is 96 procedure, should be the same. please give good rating if this is what you want.

Entry Code The system (permanent) entry code is located in three places:

• on the owner's wallet code card (in glove compartment)
• electronically accessible by requesting the remote anti-theft personality module KEYCODE PID on the New Generation Star (NGS) Tester
• on the remote anti-theft personality module housing

The remote anti-theft personality module is programmed at the factory with a five-digit entry code. A replacement remote anti-theft personality module includes replacement labels and a new owner's code card. To turn on the interior lamps and light all illuminated components:

• press any button on the keyless entry keypad (14A626).

To program a temporary access code:

• Enter the permanent code on the keyless entry keypad.
• Press button 1/2 within 5 seconds of last digit of permanent code. (This alerts system to accept temporary code.)
• Enter alternate five-digit code. Do not exceed 5 seconds between entering digits or between pressing the 1/2 key and entering the first digit.

The Unlock Code and the device unit's serial number are listed on the anti-theft ID card that comes with the vehicle. The card is usually placed in the glove box at the time of delivery. Use the Unlock Code listed on this card. For certain models, the dealer may have placed a label with the device serial number on the glove box. ----------------- If you cant find it, you need 3 things

or you can pull out the radio, take it to the service dept. of a honda dealership and ask them if then can look up the code for you. they might ask you for your vehicles VIN, so you might wanna have that written down.
i always get a marker (Sharpie) and write the code on the top of the radio. that way you can't loose it.

you need an 'anti-theft' code to reactivate the radio. whenever the electrical power to the radio is interrupted the system "thinks" that the radio has been stolen and it goes into anti-theft mode.

if you purchased the car new, then you might find a white card about the size of a credit card with the owners manual or papers you received when you bought it. that card would have the anti-theft code on it.

if you can't find the card, call the dealer you bought it from. they may have the code on file from when they sold the car. however, most dealers only keep records for 7 years and often in remote storage locations so don't count on them having the code.

if you don't have the card, look inside the glove box for a white label about 1" long and 1/2" high. It may have two rows of numbers or just one. If it has two rows, the 5 digit number on the top is your anti-theft code. if it has one row of numbers about 9 charactors long, it is the serial number for the radio.

if you have only the serial number for the radio, you can call any Acura dealer, give it to them and ask them to look up the radio code on their Acura system. each radio code is specific to the serial number of the radio; there is no 'universal' code.

if you can't find the tag in the glove box, look under the rear trunk lid. if the car has an ashtray, pull it out and look at the backside or underside of the ashtray. the dealers put the tags in a variety of places when they did the initial inspection on the car.

if you can't find the tags, then try this. with the key in the igntion switch and the key ON but the rado turned OFF, hold in the station select buttons number 1 & 6 with your right hand. then, while holding those buttons in, turn the radio ON with your other hand. You should see a series of 5 charactors on the display starting with the letter U and followed by 4 numbers. write them down. then the display will change to a second set of 5 charactors starting with the letter L and 4 numbers. write them down. then call the honda dealer and give them those numbers--those numbers are the serial number of the radio.

if all else fails, the radio will have to be removed to get the serial number off of the manufacturer plate on the back of the radio. dealerships will not charge to retrieve the code for you but will charge to remove the radio.

hope that gives you some direction. I think you'll be able to get the radio activated again. one note--you have 3 shots to enter the code correctly or you'll get an error message. if you get that, disconnect the negative battery cable and leave it off for 3 minutes to clear the error mode. then reconnect the cable and you can then enter the code.
