The rear door buttons don't work if the fob is not working.
The mechanical key is released from the smartkey fob at the press of a recessed button and used for entrance through the driver's door only. There is no key lock on my glove compartment door. I don't think that the smartkey has a valet option. If the smartkey key battery is depleted, the smart key can be used to start the engine by touching the emblem side to the stop/start button and operating the normal start sequence within ten seconds (as described in the manual). If the smartkey fob is not active due to water damage, I would suspect that the emergency start procedure described previously, may not work if parts of the fob's circuitry are compromised.
Your second fob may help if available. The batteries will last 1 to 2 years whether in the fob or lying around in your storage, so don't buy them too early. Has anyone replaced batteries yet (my Venza is just a year old as of yesterday).
