Sienna 2003 remote key

Hi Guys ,
until yesterday when i was locking or unlocking car doors with remote key , headlights were blinking .Not anymore ... any advise ?

Thanks a lot.

hi,
you've probably already tried this, but the first step is to replace the battery (~$5 at your local store)

if that's not it, see "keyless remote programming" threads for programming instructions to reprogram your remotes... "big yellow monkey" posted programming instructions for the 03 siennas that should work, as long as you don't have the power sliding door remotes.

i'm having the same problem with my 99 XLE keyless remotes but need someone to post the programming instructions for the remotes that DO HAVE the power sliding door.

good luck!
