Finding the Door Security Code for a Ford Explorer


If you’ve ever locked the keys inside a Ford Explorer XLT or Eddie Bauer, you know the benefit of having the door keypad to unlock it. What do you do if you’ve lost the code?

XLT and Eddie Bauer model Ford Explorers are equipped with a five-button key pad on the driver’s side door that may be used to gain entry to the vehicle or to manually lock all of the doors from that side in the event that the owner misplaces their keys or locks them in the vehicle.  This feature is great for those times when you’d otherwise be stranded outside the vehicle.

If you have forgotten the code, you do have the option to pay the dealer where you purchased the Explorer and they will provide the code, but the fee is significant.  You can find the code hidden inside the Explorer, so why pay for it?  The keypad is not helpful if your keys are locked inside and you don’t know the code, but if you still have access to the interior of the vehicle, you should be able to locate the code and memorize it or write it down.  You just have to know where to look.

Hmmm... what was that code?
Open the rear hatch of the Explorer.  Inside the drivers’ side of the storage area, there is an access panel where the jack is stored.  Open this panel by twisting the knob and completely remove the panel.  You may have to remove the jack from it’s holder to see the code.

Using a flashlight, look inside the panel in the direction of the front of the vehicle.  There is a label inside with the code typed on it.  You may have to look at odd angles to see it or use a mirror to get a better look.  Write down the code and then close and lock all the doors of the Explorer.  Try entering the code to unlock the doors.  Pressing the two buttons on the far right twice simultaneously should lock all the doors.  This quick lock function is a universal feature no matter what code is assigned to unlock the doors.  If for any reason the code does not work, consult the dealer.  They may have to reprogram the keypad, which will also cost you.

Detecting Visitors in a Driveway Using Infrared Photoelectric Sensors



Sometimes you just need an extra minute to prepare for a guest’s arrival.  When the doorbell rings, it’s often too late.  Why not install an infrared photoelectric system that will alert you to the presence of a guest before they ever make it to your door?

Infrared photoelectric sensors may be used to detect objects in a number of ways.  Mounting the sender and the receiver across from each other is known as a through-beam configuration and provides the strongest beam.  Retro-reflective mounting places the sender and the receiver on the same side and bounces the infrared beam off an object when it is in close enough proximity.  Diffuse proximity mounting uses the same layout as retro reflective, but also uses a reflector on the side opposite the photo eyes.  Any of these three configurations may be used to set up a driveway monitoring system depending on what type of structures are adjacent to the driveway.

Evaluate the best location to mount the sensors.  This may be a mailbox, a fence post, a brick building, a bridge, or whatever standing structure happens to be within range of the driveway.  If you mount the photoelectric sensors in a through-beam configuration they do not need to be very close to the driveway, whereas the other two options will need to be much closer, depending on the type of photoelectric sensors used, like ten to fifteen feet.

Trace a route back to your home for burying the sensor wires, but don’t put the wires in the ground yet.  Instead, extend the wires back to the house above-the-ground and connect the photo eyes to the appropriate power source or to an external amplifier if the photoelectric system includes one.  Connect the output of the sensors to a buzzer or bell with a noise that is distinctly different from the sound that your doorbell or telephone makes so that you can easily distinguish them.  Many photoelectric amplifiers include a relay output, so connecting them to a buzzer should be as easy as connecting a mechanical switch.  See the manufacturer’s website for wiring diagrams.

Test the system using different types of cars and trucks and also people.  Adjust the sensitivity of the photoelectric system to the optimum level and mount the photo eyes at the right height from the ground to hit the midsection of most vehicles.  When everything is set correctly, bury the conduit containing the wires and do your best to conceal the photo eyes from view.  This system will provide a reliable means for detecting guests before they are standing on your doorstep and could also be interfaced with a security camera or lights.  The opportunities are unlimited.

Preparing Your Home for Overnight Visitors


Your home is your comfort zone; a place where you can unwind at the end of a long day, but is your home ready to accept overnight visitors? Follow these easy steps and be prepared for them.

Perform a thorough cleaning of the entire house.  Vacuum every inch of carpet and rugs and sweep and mop all the other floor coverings.  Use disinfectant to clean all counter tops and bathrooms.  Change the air filter in the hallway return.  Make sure each room of the house is as clean as it can possibly be.  Adjust the thermostat temperature to the most comfortable setting for the current season.  If you have pets, find out whether your guest has any pet allergies so that you’ll know whether or not to keep them separated.

Wash and fold your best towels and leave enough stacked in the bathroom for each day that your visitor will be there.  Prepare a basket with soap, shampoo, mouthwash, toothpaste, and shaving supplies, in case they forget a few things.  Buy plenty of snacks and drinks and have them chilled well in advance.  Rent a few movies as back-up entertainment and leave them near the television.  If your visitor has given you any special gifts in the past, find them, dust them off, and leave them out on display to show how much you appreciate the gift.

Create a guest account on your computer and be sure to leave the computer logged into that account so that your visitor may check their email and use the Internet without having access to your personal files and information.  It is a good idea to create a restore point on computers running Windows operating system and back up any important files to external storage devices.  Lock all filing cabinets and search the house for documents like bank statements or personal mail and put all of it away.  Now is a good time to shred any old documents that you no longer need.

When your guest arrives, give them a short tour of the house and show them to their room.  Keep the house quiet and give them plenty of time to unpack and relax.  Offer them refreshments and tell them where to find you when they are ready.  If you will be eating out, prepare a list of restaurants in advance and allow your guest to choose their favorite type of food.  Enjoy your time together without worrying about the condition of your home and without the stress of making last-minute decisions.
