I have done everything to try to get my 2002 4x4 limited 4runner key programed and it still will not take my new keyless fob ment for (hyq12ban/hyq12bb/,hyq1512y) replacements .
-will go into program mode flawlessly"key in +out lock/ unlock 5 times , door close to open ,repeat lock/unlock sequence ,turn key on position twice pull key - locks will and do cycle once(locks the Unlocks)
But then when I press the lock and unlock buttons simultaneously fob , the locks imediatly cycle twice before I get a chance to hit the fob lock button for one sec, indicating that the fob was not programed
Now sometimes it does program but does not 100% work correctly it will cherp and lock and unlock , but then it will set the alarm off randomly then the key fob stops working all together and then the alarm is triggered
the only way to correct this is to erase all the fob remote in system ( same as programming but instead of 2 on position turns you do it 5 times (locks cycle 5 times indicating it has removed all key fob information)
Any ideas what could be wrong
(Just bought the 4runner trying to get everything back to oem. Shape)
