You can reset a new password just like you would the initial one. You don�t need to know the code to enter programming mode and once reprogrammed the old code will be erased.

The programming instructions are in your Owner's Manual and may also be on the unit itself.

Or you can use the information below to program the Keyless. Take care not to hold down the SRT Button too long or you may erase all memory and then have to re-program your remotes as well.

If you can not get a component to program then either the keyless or one of the remotes has a low battery or is failing. Again, the information below should help.
