EXHIBIT 31.2


                           CERTIFICATION

I, Diane C.A. Rosler, Principal Financial Officer, certify, that:

     1.   I have reviewed this annual report on Form 10K for the
period ended December 31, 2006, of First Keystone Corporation.

   2.   Based on my knowledge, the annual report does not
contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements made, in light of
the circumstances under which such statements were made, not
misleading with respect to the period covered by this annual
report;

   3.   Based on my knowledge, the financial statements, and
other financial information included in this annual report, fairly
present in all material respects the financial condition, results
of operations and cash flows of the registrant as of, and for, the
periods presented in this annual report;

   4.   The registrant's other certifying officer and I are
responsible for establishing and maintaining disclosure controls
and procedures (as defined in Exchange Act Rules 13a-15(e) and
     15d-15(e)) and internal control over financial reporting (as defined in
Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and
we have:

         a)   designed such disclosure controls and procedures, or
     caused such disclosure controls and procedures to be designed
     under our supervision, to ensure that material information
     relating to the registrant, including its consolidated
     subsidiaries, is made known to us by others within those
     entities, particularly during the period in which this annual
     report is being prepared;

         b)   designed such internal control over financial
     reporting, or caused such internal control over financial
     reporting to be designed under our supervision, to provide
     reasonable assurance regarding the reliability of financial
     reporting and the preparation of financial statements for
     external purposes in accordance with generally accepted
     accounting principles;

         c)   evaluated the effectiveness of the registrant's
     disclosure controls and procedures and presented in this
     annual report our conclusions about the effectiveness of the
     disclosure controls and procedures, as of the end of the
     period covered by this annual report based upon such
     evaluation; and

         d)   disclosed in this report any change in the
     registrant's internal control over financial reporting that
     occurred during the registrant's most recent fiscal quarter
     that has materially affected, or is reasonably likely to
     materially affect, the registrant's internal control over
     financial reporting; and

     5.   The registrant's other certifying officer and I have
disclosed, based on our most recent evaluation, of internal control
over financial reporting, to the registrant's auditors and the
audit committee of the registrant's board of directors (or persons
performing the equivalent functions):

         a)   all significant deficiencies and material weaknesses
     in the design or operation of internal control over financial
     reporting which are reasonably likely to adversely affect the
     registrant's ability to record, process, summarize and report
     financial information; and

         b)   any fraud, whether or not material, that involves
     management or other employees who have a significant role in
     the registrant's internal control over financial reporting.
