I presume you're also using RefTeX which is plugged into AUCTeX.  In
this case, AUCTeX transfers the job of inserting labels to RefTeX which
in return uses the values in `reftex-section-prefixes':

,----[ C-h v reftex-section-prefixes RET ]
| reftex-section-prefixes is a variable defined in ‘reftex-vars.el’.
| Its value is ((0 . "part:") (1 . "cha:") (t . "sec:"))
|
|   You can customize this variable.
|
| Documentation:
| Prefixes for section labels.
| When the label prefix given in an entry in ‘reftex-label-alist’ contains ‘%S’,
| this list is used to determine the correct prefix string depending on the
| current section level.
| The list is an alist, with each entry of the form (KEY . PREFIX)
| Possible keys are sectioning macro names like ‘chapter’, section levels
| (as given in ‘reftex-section-levels’), and t for the default.
`----

Customize this variable acc. to your needs and you should be set.

Best, Arash
