Question about 1993 Mercedes-Benz Mercedes Benz 400 Class

1 Answer

I have a 1993 W140 400SE with a 4-battery infrared remote control key which does not work (the key works, not the infrared part). A local MB dealer quoted me AUD$500 to $600 to replace the remote but this seems excessive to me (I heard in the UK they were about 60 pounds sterling or AUD$110). What options do I have to replace this remote?

How do I re-program my Remote Control with automatic starter on my 2009 Town and Country Van


My experience with frequently-used vehicle remotes (any make) is this:
1. When relatively new or in good condition, if remote stops working, the button battery inside is dead or too low.

2. If battery is new, & remote still doesn't work, a solder joint on the circuit board inside may have come loose or broken.(You can try re-soldering using a low-heat pencil iron & thin RESIN-core solder -- even if you're not great at it, what do you have to lose?)

3. It's rather unusual for even an older, well-used remote to simply lose its programming.If this is the problem, it may be cheaper to buy a new after-market remote (or pair of remotes) that you can program yourself (only works with some brands & years of vehicles, so READ THE INSTRUCTIONS ON THEIR WEBSITE BEFORE BUYING AN AFTER-MARKET REMOTE), instead of going to the dealer for a normally HIGH-priced programming job.

4. Used OEM remotes that match yours exactly (check the part # of your remote & the used one you're considering) can often be purchased from a local auto wrecker (now called "auto recycler") for cheap ($5 to $10 is common), but will need programming.I always go thru the many they have, looking for one that appears new or like-new.

5. IF YOU MUST GET PROGRAMMING FROM A DEALER, usually it's the SAME PRICE whether you have 1 remote or several remotes/keys programmed at the same time.Since dealer programming is pricey, I always have 3-4 remotes and/or chip-keys programmed at the same time.(My dear wife loses chip-keys & remotes from time-to-time, so I keep a few spares on-hand.I've found inexpensive after-market chip-key blanks at some key cutters and/or auto parts stores, altho they still require programming after the copy is cut from yours.)

CAUTION
:Some OEM anti-theft systems require that ALL remotes & chip-keys be programmed/re-programmed at the same time, whether they're original, used or new.Determine this IN ADVANCE, so you know what you're faced with.The good news is that for those vehicle manufacturers, dealers normally don't charge more to program/re-program multiple remotes and/or chip-keys, if all are being done AT THE SAME TIME.

6. If all else fails & you MUST buy a new OEM remote (which will require programming), try 2 things -- First, see if the dealer will make you a package deal on buying the remote (or 2 remotes, or a remote & a chip-key) AND doing the programming for a lower combined price.Second, it may be cheaper to buy a new OEM remote from a dealer who's had one in stock for a long time & wants to blow it out (or buy from online OEM seller) & then pay the normal programming price.See the CAUTION above.

There are lots of options here, so hopefully something is useful to you.

Key fob on my jeep grand cherokee is not working


Your key fob remote control contains a digital watch battery. Carefully remove the rear of the fob to replace the battery. You can take it to your local Sears watch department or your local Radio Shack if you are hesitant to try to remove the rear of the fob. They will do it for you. If a dead battery is not your problem, take the fob to the parts department of your local Jeep dealer or lock smith [along with your registration for proof of ownership & VIN number] They can test the remote to see if it's dead and needs replacement.

Mercedes c class 2001 elegance, key fob not working everytime its pressed. I have had the batteries checked and they are still working fine, any advice as to what is causing this?


Most likely needs to be re matched to the car.

Two bits of info off the net for you

C CLASS (1993-1997), E CLASS (1995-1997), SLK (1996-)
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds manually lock or unlock the vehicle using the passenger's door lock or the boot lock.
Alternative method
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds, switch the ignition ON.
Alternative method
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds, turn the ignition switch to position II.


and

1. Place key in ignition lock and turn to position 2 [all ignition lights on]
2: Turn key to off position and remove from ignition.
3. Within 10 seconds:
3a: press the Close [Lock] button and hold it down
3b: while the Close button is still depressed simultaneously press the Open [Unlock] button. Press and release the Open button 5 times [still holding the Close button down]
3c: Release both the Close and the Open buttons at the same time, and immediately push any of the two Open buttons once [i.e. either the Open doors or the Open Tailgate]

This information is for the resetting of a previously synchronised key to match the security system after batteries have been removed or replaced. This information does not work with new keys which it seems must be taken to a person with a key synchronisation device [or a super-ripoff-expensive MB dealer]

hope this helps

My remote key will not open the doors


I have to ask this question. Have you changed the battery? if the battery is good have you tried any other remotes. If one remote works and the other does not. The remote is probably bad. If all remotes do not work then the cars ecu for the door control could be bad or as simple as a fuse.

I am trying to locate another remote for my 1993 Camry Ultima


Best place to look is on ebay. Find a reputabe seller, be sure to match the FCC ID number on the back of your current key to ensure compatability. You can probably get one through a local Toyota dealer but will cost much more.

Will not unlock with key fob, have replaced batteries


this usually happens when the battery has been disconnected from the vehicle, what happens is when the battery is disconnected the locking system fitted to the car has a pass-code that only the key-fob can access, as a result of the battery being removed the pass-code for the locking system on the car resets and does not recognise the fob being used. Your best chance to get this sorted is to take it into your local garage/dealer and get the fob linked back up to the cars locking system.

My toyota 2007 yaris 4dr sedan keyless entry not working


If your keyless entry remote has never worked it either needs to be programmed to the vehicle or it is the incorrect remote part number for they vehicle. First step is to call your local dealership, ask for service, then verify your vehicle came equipped with the keyless entry option and verify the key fob part number. When calling the dealer have your vin# handy, they will need that. Once you have verified your vehicle has keyless entry option and you have the correct keyless entry remote part number then find a locksmith to program the remote to your vehicle. We suggest a locksmith because they are usually more affordable than the dealer and they come to you.

If your keyless entry remote has worked before and it just stopped working, here are a few tips to try to get it working again:

1) Change the battery
Batteries don't last forever, you'll be surprised how often it's just a dead battery! Search our YouTube channel on how to change a key fob battery for your specific year, make, and model!

2) Wipe the board
The board inside your remote can get a lot more filthy than you think! When the board is dirty it can prohibit the contact to the circuit board when you push down on the button. Simply wiping the circuit board off can make your key fob like new again!

3) Get it checked
Go to your local hardware store like AutoZone or Oreilly's. They usually have a RF frequency tester. This little gadget will let you know if your key fob is sending a signal. If it is, you may need to reprogram your key fob to your vehicle

4) The old car battery reset trick
I know this sounds absurd, but it works sometimes and is worth trying. If you exhausted all of the options above, disconnect both terminals on your car battery for 10 minutes. Then reconnect them and try your key fob. This has worked for many people and I have no idea why. If you do, please comment below to explain.

5) New fob!
It might be time for a new key fob! No need to dread over the expensive costs of a new key fob, at Keyless Entry Remote Fob Inc., you can get a refurbished one for a very affordable price! You won't even be able to tell the difference. Just search your vehicle make, model, and year to purchase a key fob or give us a call at 402-671-5100.
