Security and convenience
NXP’s keyless access and immobilizer solutions
Electrical systems, with their ability to make
dramatic improvements in car safety, security,
and convenience, have become essential to
car design.
At NXP, we offer a broad range of innovative solutions that enhance the
way electrical systems can benefit a vehicle’s architecture. In particular,
our access and immobilizer portfolio includes a variety of cost-efficient
technologies that make cars more secure, and make car access more
convenient.
We take car access to the next level, with keyless entry/go applications
that facilitate system design, deliver maximum system security, and offer
new options for connectivity. Our RF solutions give the added ability to
implement one- or two-way communication between the key and the car,
opening up new possibilities for monitoring vehicle status remotely.
Our application approach, which combines our ICs with full support for
a complete application, gives our customers an advantage, letting them
leverage our years of experience in automotive design and shorten time-to-
market.

Our highly integrated ICs for car access and immobilizer applications combine
secure operation, convenience, and flexibility. The result is a portfolio of solutions
that are ideal for today’s advanced, feature-rich key designs.
Keyless entry/go family
Our market-leading chipsets for keyless entry/go deliver the ultimate in security and convenience, unlocking
the car automatically without any direct action by the key holder. Equipped with embedded low-power
processors, these cost-effective solutions enable a range of convenient features, including push-to-start.
They offer excellent LF sensitivity, sophisticated wake-up detection, ultra-low power consumption and
integrate 3D LF and RISC controller ICs.
Immobilizer and remote keyless entry family
We offer a range of devices, from standalone immobilizer transponders to fully integrated immobilizer
and remote keyless entry ICs, so you can choose exactly the right performance and functionality for your
application. Our remote keyless entry solutions include options with an integrated UHF transmitter and
transponder coil, and our basestation solutions simplify the design of immobilizer systems.
RF devices
To complement our keyless entry portfolio, we offer a full range of sophisticated RF devices for
communication in the ISM band, up to 1 GHz. We support cutting-edge designs for car access, with
extensive system know-how and a range of solutions – from a transmitter based on a fractional-N PLL to
transceiver and receiver solutions that integrate a variable bandwidth filter and a low-power polling timer.
Connectivity with the key of the future
Our latest keyless entry/go ICs offer innovative connectivity, employing an ISO14443 interface compatible
with Near Field Communication (NFC) devices. They make it possible for an NFC enabled mobile phone to
query vehicle status via the car key, and enable remote configuration of the car.
