If you follow the instructions in the following article, you can reset the password:

Remember, once the config register has been set inside of RONMON, you need to reboot the switch and complete the rest of the instructions...

Hi

try these::
(1) switch the power on, press the Ctrl+Break key within 30 seconds, prompt appears “rommon 1>” (if this prompt does not appear, switch back up, and repeat (1)).
(2) type the following command: rommon 1>confreg 0×2142
(3) initialize the switch: “rommon 2>reset”.
(4) switch#show startup-config

This will back up all of the content.

(5) switch#config mem
switch(config)#no enable secret
switch(config)#enable secret cisco
switch(config)#config-reg 0×2102¿ ;
“switch(config)#exit”;
switch#write mem
