Question about 2008 Toyota Prius

1 Answer

An 08 prius keyless entry doesn't work, changed the batteries, pushed the disable button and reset it, still no go. Any ideas?

I accidently disabled the smart key entry system by depressing the button under the steering column. Then I changed the batteries in both key fobs thinking they had been depleted. After doing some research , reset the smart entry disable button. Now the key fobs have power in them but they won't unlock the doors and the system won't start unless the electronic key in actually placed in the slot. What do I need to do besides take it to the dealer?

SOURCE: my 03 rav4 has driver door lock problems

Drive to Gondwannaland. Third exit on right. See Dealer. Reject offer. Go home and try to pry off the panel. Break screw covers. Unscrew things and pry again. Break door handle cover. Unscrew and pry. Unscrew and pry. Pop the bottom. Lift it out. Let it hang. Find the solenoid. Unplug. Hang the door cover. Drive to the parts store with a loosely-hanging door cover. Replace the solenoid. Use a hammer because you are mad! Get it together! Go to the junk yard for broken plastic parts. Cuss. Drink beer. Be glad you can lock your truck!

SOURCE: I have a 1999 Toyota Corolla and electronic key

I am having the SAME problem with my 99 Corolla, Still searching for a way to disable the factory security system, for the last two years I have the vehicle hotwired through the headlights to start it. (1 wire to battery positive, 1 wire to starter hot lead, touch them together.) unfortunately this has proven very dangerous as the vehicle will start even in gear, and take off without a driver. additionally, because the alarm is going off continuously, the battery dies if not disconnected after every use. I found the fuse in the relay box that disbles the alarm, and the car starts fine, unfortunately, It it also the fuse for the alternator, so that solution will not work either. If anyone has found true way to disable the system, PLEASE offer your suggestions!

SOURCE: dealer gave me a shaved key works on starting ignition not on door lock the other three keys work on everything car doesn't have engine immoboliser removed the remote keyless entry fobs what is

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.

How do you turn off an alarm for a 2005 Saturn Ion


Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the BCM stores the CTD mode status in memory.
?€¢
To disarm the CTD system in arm pending mode, SECURITY indicator flashing and doors open, perform 1 of the following:


-
Press the UNLOCK button on the keyless entry transmitter.


-
Insert a valid key into the ignition and start the vehicle.


?€¢
To disarm the CTD system in the armed mode:


-
Press the UNLOCK button on the keyless entry transmitter.


-
Insert a valid key into the ignition and start the vehicle.


?€¢
To disarm the CTD system when activated, alarming mode.

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

2001 Mercury Villager keyless remote is malfunctioning


Keyless Entry
The keyless entry system consists of the following:
  • smart entry control(SEC)/timer module
  • keyless entry remote transmitters
  • power door lock actuators
  • body side door power door lock actuator
  • liftgate actuator
  • power door lock switches
  • door ajar switches
  • Principles of Operation
    All doors can be locked at once by turning the door key lock switch to the locked position. An individual door can be unlocked by moving the door key lock switch to the unlocked position and turning it again within five seconds; all the doors (including the liftgate) will unlock.
    The smart lock system is designed to keep the driver from locking his keys in the car. It will lock and then unlock all the doors if the smart entry control(SEC)/timer module detects the following conditions:
    • The ignition key still in the ignition.
    • A front door is open.
    • A door lock switch has been pushed to the lock position.
    The panic feature has a duration of 30 seconds from the last time the PANIC button is pressed. When locking the doors from the remote transmitter, the horn chirp/lamp flash feature can be disabled or enabled by holding the LOCK and UNLOCK buttons for two seconds. The hazards will flash three times to confirm that the feature has be enabled or disabled.
The control module probably see's an input that shouldn't be there . lock Switch , door ajar etc... Don't think it has anything to do with the remote . Some part stores have a tester to see if signal from the remote is working . Or the dealer ! Take it an see if your remote is sending a signal without you pressing any buttons .
If it is you need a new one .

My Prius 2006 will not start with the remote not in the key hole.


I had the same problem with 2007 Prius.
Before doing the resetting procedure, look under the steering wheel and see if there is a "key" button. Mine had been pushed in,inadvertently during an inspection, which immobilized the "smart" operation. Simply pushing the button solved the problem.

2008 Volkswagen Jetta keyless entry & lock problems


If the system is not working even when you press the buttons on the door, then the problem is not with the remote control. I would first check if all the fuses are ok, if they are, I would check the wiring on the door to make sure there are no wires broken of chaffed. Focus first on getting the system working with the door buttons and after that is ok, the move on to the keyless system in case it still does not work. Hope this helps.

Had car starter installed now the passlock light stays on. He took the key out while the vehicle was running. They disconnected the battery and hooked back up but that did not work.


Important: Using the power door unlock switch or manually unlocking the doors does not disable the Content Theft Deterrent (CTD) armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the body control module (BCM) stores the CTD mode status in memory.

Keyless entry on honda civic 2006 not working


The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.
