It will have to be taken into a Radio Decoding Service (such as your local Car Audio Store) where they will wire in a laptop to read the working code inside the memeory chip (EEPROM) using special software

I had someone change the radio in my 1998 camry and it did work. My battery went dead, dead and once I replaced battery the radio now doesn't work. Why>

Car radios have security codes to prevent them from being stolen. If they lose power, such as when replacing the battery, they lock out. This makes them worthless to anyone trying to steal them. You need to have the unlock code to reactivate the radio. It is provided with the vehicle at purchase, or by the retailer when selling replacements

2011 Chevy impala..battery was dead..had a jump start..but radio system want come on now..

If your radio has theft protection built in, it thinks it was stolen because its standby power was interrupted. Check the owner's manual to see if there is a special procedure for preventing this lockout when the battery is changed. Typically, it involves entering some sort of code sequence on the radio controls. If you don't know the code sequence or never set it up, you'll probably have to have a factory reset done. (Sorry, I don't know how that is done; the manufacturer keeps it secret for obvious reasons.)

Code is needed if your battery dies. It is a security feature that makes your radio worthless if stolen without the code.

Battery died put in a new one now radio wont come on

You will need to reset the wireless code to turn on the radio. Removing the battery indicates to the radio that it is being stolen and the code cuts in to make the radio worthless. The code may be in the owners hand book in the wireless section. If it is not and the radio is factory fit then the dealer will have a record of the code for the wireless fitted to that vehicle in the factory. Contact dealer customer support and get it from them

How do I figure out what code is on my jaguar car radio? My battery went dead and when it turn back on I had to put some code.

It should have been in your owners manual. Each car has a security code to prevent the radio from being stolen.

Replaced radio in my 2003 silerodo it says locked what do i do

The dealer can provide the unlock code for the *original* radio that was installed in the truck when new but if this was removed from another vehicle, you would probably need the VIN from that vehicle and you must be able to prove that this one was not stolen.
This feature is for theft prevention and is a source of trouble even for the real owner. This 'feature' appears even when the battery dies and must be replaced.

2003 Honda sportscar- battery died-restarted it now radio says "err-1"

On Hondas when power is not supplied to the radio it goes into a safe mode, this is to help prevent it from being stolen. You will need a code to input into your radio. If you call or visit your local dealership they can look up this code using your VIN, it is typically a 6 digit numerical code, you just use the preset buttons to enter it. If you bought the vehicle new you should have this number in some of your paperwork/manuals. Good day!
