Just want to know how it works

When you press a button, it broadcasts a coded ultra-high frequency radio signal. If your car is within range, the radio receiver in the remote control lock circuit decodes it. If the identity portion of the code matches the number in the receiver, then the command code (lock, unlock, or whatever the other two buttons are for) is decoded and the receiver turns on the equipment in the car that does the desired operation.

Call an Acura dealership with that serial number and they should be able to provide you the code. Or you can take it directly to the dealer but you will be charged labor.

Code of radio

there is no such thing for your van. the stereos in your van are coded through a data calibration system. If stereo is switched with a different one, most poeple will change the stereo due to the display being out. when this happens, you will need a GM tech II scanner in order to recalibrate the unit into your vehicle. some dealers will charge anything from free to 1/2 hour to calibrate the stereo. to save time you should install the radio into the van, because the calibration is done through thr OBDII connector under dash.

Kids locked up the TV, need code to unlock it.

Try this: press "Function" and "Mute" on the remote at the same time. This will unlock the channel. Do this if you want to bypass the lock to watch a certain show or channel while leaving the TV locked. All other channels will remain locked and the TV will lock again when it is turned off.
Unlock all of the channels on the TV by entering 0711 or 3308. These are the Jensen factory reset codes that will reset the TV to the original factory settings. By doing this, you will loose any information that you have stored in the TV, such as channel labels and schedules. You will have to program the TV again by going through the entire initial set up.

Radio code

Found this on another site.

General Motors coded THEFTLOCK® radios have a backup unlocking code that can be accessed by a General Motors dealer or a Delco® radio repair center if the owner programmed security code is not available. Honda, Acura and Audi anti-theft radios are examples that will require radio removal to access the radio serial number that a dealer needs to obtain the factory security code. Sometimes the original dealer for a vehicle may keep records of the radio security code for factory-coded radios.

Sounds like you may have to remove the stereo so you can see the code on the back.

Then I would take it to a local dealer and prove its yours and give them the serial number.

They should be able to decipher it for you.

First make sure that the code has not been noted somewhere within the car (underneath the ash tray, glove box , rear of sun visor etc) 

To see if your code is available here for free then the radio will have to be removed from the dashboard (and if you are lucky, someone may have written the code on the casing ) .



note: Unfortunately not all radios can be decoded using the Serial Number 

If not then try your Main Dealer ...........or take it into a Decode Service who will plug in a laptop to read/recode the memory chip (EEPROM). This takes a few minutes and shouldn`t be too expensive

Car codes

As you have most likely heard, you go to the dealer. You can also try using the net to find a site that will give you the unlock code. Price for this ranges from $3 to $20. I have been searching for sometime trying to find radio codes for the same problems with no luck. Good Luck everyone.
