EXHIBIT 31.2


                            CERTIFICATION


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

     1.   I have reviewed this quarterly report on Form 10Q for the
period ended June 30, 2007, of First Keystone Corporation.

     2.   Based on my knowledge, the quarterly 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 quarterly report.

     3.   Based on my knowledge, the financial statements, and other
financial information included in this quarterly 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 quarterly 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-14 and 15d-14) 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
     quarterly 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
     quarterly report our conclusions about the effectiveness of the
     disclosure controls and procedures, as of the end of the period
     covered by this quarterly 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, to the registrant's
auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent function):

          a)   all significant deficiencies in the design or
     operation of the internal controls which could adversely affect
     the registrant's ability to record, process, summarize and
     report financial data and have identified for the registrant's
     auditors any material weaknesses in internal controls; and

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



                           /s/ Diane C.A. Rosler
