I locked my keys in my Hybrid Highlander and tried to use my husband's keyless entry fob to open and it wouldn't open. Is this happening because of a security situation. I can't believe the battery is out in the fob. Is there anything I can do to open the car?

NO FOBS DETECTED

Keyless Entry System Description and Operation - Passive
Passive keyless entry allows entry to a locked vehicle without pressing any buttons on the keyless entry transmitter. You must only have the transmitter with you. This passive system is also part of the vehicle starting system. It allows you to start and run the vehicle having only the transmitter as your key. The passive entry and starting system use low frequency antennas in 4 different areas on the vehicle to determine the location of the transmitter. When passively opening a locked door or the rear compartment lid, you must have a programmed transmitter with you in your pocket, purse, or briefcase. As a customer opens the door handle or presses rear compartment touch pad, the low frequency antenna sends out a challenge to the keyless entry transmitter. The transmitter must be in a one meter range of the door or rear compartment lid in order to receive the challenge. If the challenge is met, the transmitter will respond, allowing the door to be unlocked and opened. Passive entry allows you to operate the following features:
• Passive door unlock/unlatch
• Passive rear compartment lid release
• Illuminated entry lamps
• Vehicle starting
The keyless entry system has the following components:
• Keyless entry transmitters
• LH and RH door antennas (part of the door handle assembly)
• Rear compartment antenna
• Console passive antenna
• Console active antenna
• Instrument Panel Module (IPM)
• Rear Integration Module (RIM)
• Remote Control Door Lock Receiver (RCDLR)
• External RF Antenna (includes coax from RCDLR to back glass)

Remote Control Door Lock Receiver (RCDLR)
The RCDLR is a multi-function module which controls all the vehicles antennas for passive keyless entry functions. The RCDLR also acts as the receiver for active keyless entry and tire pressure monitoring (TPM) functions, as well as controlling all immobilizer functions.
The RCDLR's RF antenna is located in the back glass, and there is a coax cable connecting the glass antenna to the module located in the trunk.

Your best bet , take it to a qualified repair shop that has the factory Tech 2 scan tool or someother professional type scanner that can read • Rear Integration Module (RIM) DTC'S - diagnostic trouble codes .

Testing would need to be done , scan tool hooked up checking DTC'S - diagnostic trouble codes . View data etc...
Keyless Entry System Description and Operation - Active
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock/unlock a door or open the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message. A low transmitter battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas, such as gas stations that use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following features:
• Door lock/unlock
• Rear compartment lid release
• Illuminated entry lamps
• Panic alarm/Vehicle locator
• Remote vehicle start

Your best bet , take it to a qualified repair shop . Dealer

Many times the dealer gives you a valet key made to give to the vet to park your car, these keys work even though the theft deterant system is active, but they will only work for short periods untill the theft system activates and imobolizes the vehicle. The system is reset when the valet brings your vehicle and you insert your normal (chiped) key.

remove grille and move latch to open hood-boost battery and use key fob to enter or have locksmith or service station use a slim jim or other type of device to unlock door

Depending on the specification of your vehicle, the FOB generally serves one (or both) of the following functions:

1) Communicate with the vehicle's Keyless Entry system (operates central locking).
2) When inserted into the ignition, the transponder within the key will communicate with the vehicle's Body computer (BEM) to validate entry, before disengaging the immobilizer - allowing the vehicle to start.

When the key fob fails, you may lose functionality of the above systems.

Keyless entry failure - usually due to flat battery in the fob. Reprogramming of keyless entry can be done without dealership assistance.

Transponder/Immobilizer failure - this requires the key fob to be re-programmed by your local dealership.


Hope this helps....

should not be using fob buttons for entry or locking for emergency only .if keyless entry walk up to car with fob do not press any buttons see if door opens then walk away from car with fob about 20m then go back to car without fob and see if door locked if so all working fine .indicators will not flash if the above dont work take back to main dealer for diagnostics keys may need to be reprogrammed

dealer only

Try "resetting" your keyless entry code. Which is a fancy way of explaining that I broke my keyless entry key fob and had to order a new one. It came w/ instructions explaining how to get the new fob to speak to the car's computer. It was weird (turn key on and off 3 times, open and close door three times, etc. **I'm sure my neighbors were watching and laughing**), but it worked. I'll scan and email you the insrtuctions if you wish. Dan: [email protected]
