How Much Does a Seat Replacement Key Cost?
Losing your car key can be an unpleasant experience. Getting a replacement key through the dealer can be costly as well. seat key has specialised technicians who know the Seat models and are able to assist you at an affordable rate.
We've all had that embarrassing moment where we reach back into the car to take off an infant's seat, only to fail. It's embarrassing, frustrating, and happens to everyone.
Keys
Lost car keys are an everyday occurrence and can be a major problem. However the process of getting a replacement key from a dealer is expensive. UK Auto Locksmiths can offer a much cheaper alternative, and they'll be equipped with the latest technology and tools to help you out. In order to allow them to do the task, you will only require an VIN and proof of ownership. They'll also need know the type of key that you require. They can supply flip keys, remotes and even Fobs. They are also able to help you with the programming of any new keys.
Remotes
Most Seat drivers keep a spare remote in the house or garage, but when they lose it getting replacement keys from a dealer is expensive and time consuming. This is because most dealers will programme the key using the car's computer which will need to be reset. However, many people buy second-hand keys off the internet that are not programmed to their car. This can be a much cheaper alternative to going to the dealer. But, these key will not start the car because they will not have a transponder chip inside them. You can see the chip (yellow) in this picture below, it is a Dual Inline Package or DIP 18 pin chip. There are also a diode, transistor and resonator, all these parts make up the key's circuit.
Immobilisers
As car immobilisers became popular in the late nineties, car theft rates began to drop, however thieves are savvy and always seeking ways to circumvent security systems. The initial immobilisers were defeated by using a scanner in order to find the code on the chip and then copying it onto a blank key. However, technology has advanced and thieves have had to come up new tricks.
Fortunately the majority of the immobilisers that we supply and fit are Thatcham Cat 2 approved. The Thatcham Research organisation has tested and certified them. This non-profit organisation is the system of grading and approval for aftermarket alarms and security devices, including car immobilisers.
When the Thatcham approved system is activated, it will transmit a coded signal to the Engine Management System (EMS) of the vehicle, which stops the engine from starting without the proper key. This means that if the vehicle has been "hot wired" after entry, the engine will cut out within 30 seconds, rendering it impossible to start.
As with a computer the immobiliser can be affected and the battery inside or the key fob could need to be replaced. The best option is always to hire a professional to carry out the task as it will ensure that everything is fitted correctly and that it functions.
Transponders
A transponder is a piece of equipment that sends back an identifying signal when it is questioned. This helps maintain separation between aircraft and identifies an aircraft to air traffic controllers if it is using an active radar system. The information that the transponder transmits back is different depending on the type of system.
Transponders are also utilized in space vehicles and satellites to connect with Earth-based systems like cell phone networks and other communication networks. These devices receive signals across a variety of frequencies, and then retransmit signals on a different frequency, just like repeaters function in land-based cell phone networks.
Sophisticated passive transponders are often found on board aircraft. They monitor the status of flight and provide navigational information such as the aircraft's location speed, altitude, and speed. Transponders are able to provide information that air traffic controllers utilize to control flight paths, and ensure safety.

Many keys for personal use have transponder chips in addition to transponders for aircraft. These chips don't require batteries, and are therefore passive. This allows the ECU to read the transponder's signal when it is put into the ignition lock.
Most airplanes have a switch on the flight deck, which allows pilots to turn on or off their transponders. They can also select a "ident" mode that allows the transponder transmit its unique squawk codes. This helps it stand out in the crowded air-traffic control screen.
