I can't get the key FOB's on the 1999 LS400 to open the doors, or trunk, but I can lock the doors with them. Can someone tell me what might be the problem?

I just recently bought this car, and it was in this condition when I bought it. There is another problem going on concurrently, that is there is an erroneous Windshield Washer Fluid low message, in spite of the fat that the fluid is topped off.

    I will check on my washer sensor, that makes sense.

    To clarify my situation on my 99 ls400, I can lock the door with both key fobs remotely, but I cannot unlock either the doors, or the truck using the FOB remotely in other words. ALL entry is possible with the key, and nothing else seems problematic.

    I tried several times to do the reprogramming method I have found on these boards. Thanks for all the kind responses, we are already soooo in love with this very well kept 400, which btw has 270,000 on her.

    I neglected to mention, yes the lock unlock works from the operator control panel on the door. I have not found anything other than the stuttering steering wheel as it goes up, in terms of problems, aside from the windshield washer erroneous indicator which I have mentioned previously.

SOURCE: Car will not unlock.

To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.

SOURCE: Low Washer fluid warning light came on my Lexus

There is a little float mechanism inside the washer tank that is probably stuck or binding. If the wiper/washers work, you have power to the fluid tank.
Pull of the top and see if you can locate it. You might need a piece of flexible, fine wire to GENTLY help it along...

Both doors will not unlock with the key? sounds like the lock motors are jammed this is common on your model after years of service, try turning the key with as much force as you can without feeling it bend, this should overcome the frozen lock rod motors

The key of my Honda only locks the door and opens the trunk starts the car thats it doesnt work for anything else

Where else do you have locks? A locking glove compartment often has a separate key. The main key is supposed to open the door, open the trunk and start the vehicle. The other key is a Valet Key, the key is intended for people to give to valets to park their cars or to repair shops to use. The valet key will open the car door and start the car but will prevent someone from unlocking the glove box or the trunk.

Wireless Key Remote door & trunk opener won't work with trunk anymore

When you press the trunk open button, do you hear any "release" noise come from the trunk area? The issue may be a bad battery in the key fob OR there could be an issue with the transmitter located inside the vehicle. Do the doors lock and unlock properly? is the vehicle equipped with security or immobilizer? please advise

Trunk won't open

Lower the back seat and crawl into the trunk and see what the latch is doing when you activate the key fob. the trunk lid will have to be open to enable any repairs. Also an emergency release cable is probably visible (yellow handle) inside the trunk and will Open the trunk lid.

My trunk popped open for no reason at all on 3 different occasions. Twice when I went down to the garage it was open. (I keep the doors unlocked in the garage so I didn't hit the remote at all). And...

Most often I'v encountered a 'sensitive' button (trunk open) on the key fob. Did you have the key fob in your pocked or purse (no offense, don't know your gender). Check the fob for 'sensitivity' of the 'trunk open' button. This could be where the issue/problem is.

1999 porsche 996 replaced key fob battery disconnected battery now trunk releses are locked and cant access battery.How do you open frt trunk manually

Assuming the car battery is ok (if not, buy a male to male cigarette lighter at the auto store and connect to another car until charged enough to unlock the doors...but don't try to crank the ignition!). The trunks won't open if the battery went dead with the alarm set because arming the alarm physically locks the releases.

Sounds like the key code is switched off because you replaced the key fob battery. Try unlocking the car manual with the key in the door lock. Then switch the ignition on to reactive the keyless entry. If this does not work, you might also try pressing the fob unlock button with the key in the door lock until the dash led flashes.

But a used 2006 solara but key fob does not remotely open trunk. Any suggestions?

Yes, insure that you have power to the trunk lock inside trunk, If not could be lose/broken wire or shot fuse. I am sure the key fob does work for the doors? If not have key fob battery replaced. Also, a quick check on power to trunk lock, check to see if have remote power button inside car, if it works power is good. Defective key fob would then be indicated.

Keys lock in trunk alarm will not allow trunk switch to lock

The solution is to pull out the back seat to get into the trunk. There are two bolts holding the bottom part of back seat (bolts located between bottom and top sections). Then pull out bottom section of back seat and you see the hinge for the top section, remove the bolts and then you can lift up and access the trunk. It's not that hard.
