Question about Smart Cars & Trucks

1 Answer

I can't open, lock and turn the engine with the smart key in MB R500. What is the problem?

I tried to charge the battery in the car and it could not be charged. There was a beep inside the car the first time after the night when I found out the remote does not work. What do I do? Is the car battery dead for good, what about the snart key?

If you can get to the battery, check to see if the cell covers can be removed. With a flashlight, not a match(!), look into the cells, if the plates are not covered completely, add distilled water to the bottom of the ring above the plates. Check all 6, the 2nd from positive is usually the first one to be low. After filling cells, If this is the case, then slow charge the battery and see if it restores it to normal. If not, the battery can be checked free at many auto parts stores, using either a Hydrometer or load test/meter. Hope this helps.

SOURCE: The battery is completly dead and my keys are

Why would you need to charge the battery; do you have a door remote you could use if the battery was OK?

If im not mistaken,your car should have an alarm reset/override.Below the steering column,on the dash should be a slot where you put your remote transmitter to deactivate the alarm.If that works,you then need to have your remote checked and coded by a vw dealer.Good luck.

My MB ML350 stick key (metal key) wont unlock the door. The key goes in, it turns but the lock will not open.


Check the door lock fuse in the fuse panel... try the key on another door... may just be that the manual lk is malfunctioning on that door... if the other doors don't respond and the fuse is good then the key probably needs to be reprogrammed by the dealer to the door... happens when your battery dies or is replaced.

How to re-start my car after anit theft light has come on?


you need a full charged battery or battery replaced [if battery bad and not holding charge] your remote key fob will not work if battery is dead or to weak to start car but key should be able to manually open drivers door --if its not an original key new cut or worn down [may have to jiggle in door ] your anti theft/security lock will come on when you use key in door than you have a few seconds after you open door to put key in ignition and turn to on position before alarm goes off but you need to get battery issue corrected first if key still doesnt work may need to have assistance [slimjim]lock to get in

My keys lost their programms


Unlikely both keys have lost the programming.

Remove the car battery and give it a full charge, leave side light switch "on" while battery is removed to provide discharge path for the engine management system. Refit battery and try again.

My mercedes clk battery dead i cant open trunk


On the side of the smart key there is a mechanical key that slides out of one of the sides-There should be a little release lever retaining the mechanical key. It can be inserted into the trunk lock and turned to open the trunk. There are several other positions the key can be turned to place the trunk lock actuation in different modes- it should be in your owner's manual Hopefully I have been helpful

Toyota avalon 2006 key fob apparently doesn't work


It looks like you have the "Smart Key" (a small rectangular box) that does not look like a traditional key.
What you also have is a dead battery inside the Smart Key.
Look closely at the box; there is a little button on the side. Press it. This will release a small hidden key. After you remove the small key, use a small flat blade screwdriver to pry the case of the box open at the slot provided. Take the unit to a store that sells miniature batteries, and have it replaced. You will NOT have to reprogram it after the battery is changed. The life span of the miniature batteries is roughly 20 months, less if exposed to RFI, like sitting on a TV, a monitor, or other electrical device. The Smart key TRANSMITS all of the time, even when you do not press the buttons. This is why the battery only lasts 18-20 months. Let me know if this fixes your issue..
