Car Key Fob Programming in Houston

It is common for a key fob to get attention only after its failure. And while the failure is likely to result in a problem with the fob itself, it may occur in the vehicle's receiver, battery, immobilizer, or other components of the keyless entry system. Mobile key fob programming and replacement service is provided by Paul Car Key Houston for all cars in Houston area, on top of that we can program a compatible fob purchased at the dealer or elsewhere as well.

Rolling Codes, and Why a Sealed Box Does Nothing

The procurement of the correct fob is just one step since the modern day vehicle uses a security system that reacts only to authorized fobs and/or keys. As such, a new fob cannot work just like that despite having all the necessary buttons and resembling the original fob in all ways possible. Before the new fob can be used to unlock your vehicle, it needs to be programmed according to the procedure set up by the manufacturer. Some older cars allow performing onboard programming procedure, but most newer cars need specialized diagnostic tools and vehicle specific security access code. Therefore, finding out whether the replacement is compatible before programming is important.

What the Way It Fails Tells You

Symptoms exhibited by a key fob can give valuable information about the nature of the problem. If the operating range has become shorter or you have to press the button several times in order for something to happen, the problem is usually with the battery. If one particular button stopped working while others are fine, the problem may be related to a bad button, malfunctioning contact, or internal circuit board problem. Repeatedly dropping the key fob may also lead to its damage even if the electronics remain intact and if all fobs for the particular vehicle stop working, the problem may reside in the car, not the fobs. Our technician will examine the system and tell if you need a battery change, fob repair, reprogramming or replacement.

Summer Heat and Storm Water

Extreme heat characteristic for Houston weather can put strain on the battery and electronics of a fob. Exposure to direct sunlight or storage in the hot car can affect the battery and other components in the long run. Exposure to water can cause problems immediately. If you got your fob wet, do not keep pressing the buttons while it is wet. Remove the battery if possible and let the fob dry. A fob that works intermittently after water exposure may be repairable depending on the level of the damage, but a badly corroded or damaged fob will need to be replaced. Please notify our operator of the water exposure in advance, so the technician will know that he will need to inspect the existing fob and provide the replacement if necessary.

The Two Jobs a Proximity Key Does at Once

A proximity car key fob consists of two devices packed into a single case, one device will open the car as your hand gets close to the handle and the other device will serve as the credential required to bypass the immobilizer in order to start the engine. Both devices need to be programmed and if only one of them gets programmed, the car will open but it won't start. It is exactly the way the work on the ignition performed by our technicians goes. Higher prices of proximity keys are associated with more expensive parts and time that needs to be invested by the technician, especially if no components were left from the previous system and the car needs convincing to accept the new system. This is the usual task for our technicians to perform for any major manufacturer. Nothing is considered done until the handle sensor, all buttons and a successful engine start have been tested in front of you.

Which Part Is Worth Paying For

If your car is of American or Asian make, you will find an aftermarket key fob that is just as effective as the original but is much more affordable. Only some recent European models could see their residual value affected negatively by the aftermarket fob and we prefer being straight with you than selling it. If you already ordered a device on your own, bring it and we'll test it for you. There are two problems that often occur with the online orders and should be mentioned here: the device is shipped second-hand and is paired with another vehicle, and in some cases, the FCC number advertised does not match the current year of your vehicle. In both situations, nothing could be done by the technician.

Most car owners who call for a new fob replacement usually want the blade to be cut too. This is done during the same visit. No matter if you bring us a fob or we install a replacement in your place, pairing and verification will take place at your vehicle before you leave. Call us at (832) 910-9448 with the year, make and model of the vehicle, specify if there's any working key left, and be ready with your driver's license and registration.
