The Land Rover Discovery 4 (L319) ran from 2009 to 2016 and is one of the JLR platforms we are called out to most often for spare keys and lost key recovery. Its encrypted security module sits well outside what a high street locksmith can handle, which means owners are usually choosing between a main dealer slot weeks away or AJ Auto. We cover every L319 model year from 2009 to 2016, attending anywhere in the UK with full dealer level JLR diagnostic kit. Same day key programming in almost every case, with no lock module replacement and no need to recover the vehicle anywhere.
For a Discovery 4 spare key or a replacement for a damaged remote, our mobile technicians come to your driveway, office car park or wherever the vehicle is parked. We cut the blade, perform a clean digital pairing between the new fob and your vehicle’s security module, and confirm everything works in front of you including keyless start, central locking and the alarm. Your existing keys are left fully functional, so you finish the job with both old and new working at the same time.
For an all keys lost callout we skip the parts of the process that cost most owners several days. There is no tow, no recovery and no waiting for a workshop slot. We arrive at your location with the correct hardware already in the van, plug into the immobiliser, clear the old key memory and programme new remotes on site. Most attendances are completed in around an hour. Parts and programming are covered by a 12 month warranty, and the price is fixed and agreed up front so the quote you are given on the phone is exactly what you pay on the day.
How quickly can you replace a Land Rover Discovery 4 (L319) key on site?
On the L319 we are typically finished in 5 to 10 minutes for a spare key when you have a working remote, and 20 to 40 minutes for an all keys lost callout on a locked Discovery 4. Every job is done by an experienced JLR specialist using dealer level diagnostic tools, which makes us one of the fastest same day L319 services in the country.
Our Discovery 4 came with 2 keys, can you add a 3rd or 4th for other drivers in the household or business?
Yes. We can pair fresh keys for additional drivers without affecting any of the existing fobs, so anyone who already has a working key keeps the same functionality. The L319 supports multiple paired remotes within the security module limit, plenty for a family with several drivers or a small business running the Discovery 4 as a shared utility vehicle. We confirm the V5C registered keeper before adding any keys, in line with our standard ownership checks.
I lost my Discovery 4 keys on a farm or out in the field, can you attend somewhere off the public road?
Yes. L319 callouts on farms, equestrian yards, woodland tracks and other off road sites are routine for us. We cover the whole UK and as long as we can physically reach the vehicle in our van we can pair a fresh key in around 20 to 40 minutes for an all keys lost situation. There is no need to drag the Discovery 4 back to hard standing or a dealer workshop first.
My Discovery 4 has done over 150,000 miles and the fob has been through everything, is it on borrowed time?
On a heavily used L319 the smart key is often one of the first things to fail. After about 8 years of service the internal electronics start to drift regardless of mileage, but a hard working fob that has lived in pockets full of grit, water and farm dust tends to fail earlier than that. A fresh genuine paired remote solves it cleanly on site, comes with a 12 month parts and labour warranty, and avoids the intermittent start and unlock faults that a dying fob produces.
The dealer is quoting a security module replacement on my Discovery 4 before they will programme any keys, is that worth doing on a working vehicle?
On a Discovery 4 that earns its keep in regular use the answer is almost always no. We attend L319s where a Land Rover dealer has insisted on a locked module needing replacement, and finish the key programming on the same visit using specialist JLR tooling without removing the original module. Genuine module failure on the L319 is rare. Particularly on a vehicle you cannot afford to have off the road for a workshop slot, a JLR specialist callout is a faster and less invasive route.
